Military Other Acronyms

In the joint context, refers either to the 1993 Chemical Weapons Convention (the multilateral treaty prohibiting the development, production, stockpiling, and use of chemical weapons, in force since 1997 with the Organisation for the Prohibition of Chemical Weapons as the implementing body) or to the Composite Warfare Commander — the Navy doctrinal framework under which a battle group or strike group commander delegates warfare-area responsibility to subordinate Composite Warfare Commanders (CWCs).

"CWC — either the Chemical Weapons Convention treaty or the Navy's Composite Warfare Commander construct."

CWC is one of those acronyms whose two meanings live in entirely different parts of the DoD universe and rarely get confused in practice. The Chemical Weapons Convention is the 1993 multilateral treaty banning chemical weapons; the OPCW in The Hague is the implementing body; the US is a state party with declared and now-destroyed chemical-weapons stockpiles. The Composite Warfare Commander construct is the Navy framework under which a strike group commander delegates specific warfare areas (air defense, anti-submarine warfare, surface warfare, information warfare, strike) to designated CWCs (typically captains and commanders in the strike group) who then exercise tactical control over assigned forces. Context disambiguates: chemical-weapons articles in arms-control journals use the first meaning; Navy operational doctrine uses the second.

A phrase and accompanying doodle — a bald, long-nosed man peering over a wall — that spread among American service members during World War II, traced by a 1946 verification contest to James J. Kilroy, a shipyard inspector who chalked the phrase on ships he had checked at the Fore River Shipyard.

"A shipyard inspector's chalk mark turned into the most-traveled piece of American graffiti in history."

A quality-control inspector marking hulls he'd checked at a Massachusetts shipyard turned into a phrase GIs scrawled on every wall, latrine, and beachhead they reached from North Africa to the Pacific — the joke being that "Kilroy" had somehow already been there first, no matter how remote the location. More than 40 people claimed credit when a 1946 contest tried to settle it; James Kilroy won because riveters and shipyard officials could actually back up his story. It's one of the few pieces of service member folklore from that war that's still recognizable eight decades later — a running joke about omnipresence and boredom that turned into a piece of Americana nobody had to invent.

The traditional nickname of the US Army Field Artillery branch, reflecting artillery's historical role as the highest casualty-producing and often decisive weapons system on modern battlefields since the introduction of indirect fire methods before World War I.

"Infantry closes with the enemy. Artillery decides whether they're still standing when it happens."

Infantry calls itself the Queen of Battle and argues it does the actual closing-with-and-destroying; artillery calls itself the King and points out that indirect fire has produced more casualties than any other weapons system on the battlefield since before World War I. It's an old rivalry, mostly good-natured, occasionally not, and it shows up on unit crests, branch insignia, and the sleeve of every red-leg who will absolutely bring it up unprompted at the bar. The nickname isn't just branch pride — call for fire missions still decide a lot of fights the infantry gets credit for, and the artillery community has never stopped reminding everyone of that.

Widely used, informal military slang — most associated with Army and Marine Corps infantry culture — for any service member whose job is not front-line combat arms, tracing to Civil War-era "pogue" and now applied broadly across support, staff, and non-infantry occupational specialties.

""POG" — the affectionate-or-not label infantry culture uses for everyone who is not infantry."

POG isn't in the DoD Dictionary — it's living service culture, and it's genuinely contested. Plenty of veterans call it harmless ribbing between combat arms and everyone else; plenty of intel analysts, mechanics, medics, and logistics specialists experience it as a real dig at a job that was no less essential, and often no less dangerous. The word traces back to "pogue," Civil War-era Gaelic slang from Irish-American sailors, aimed at those who stayed close to home while the infantry deployed and got the attention they didn't. What hasn't changed is the divide it marks — combat arms culture has always drawn a hard line around who was actually outside the wire — and that line shapes daily respect and even promotion dynamics more than most recruiters will admit.

A US Army publication, running from June 1951 to September 2024, that used comic-book-style illustration to teach preventive maintenance, supply, and safety procedures for military equipment — originally created as a "postscript" to technical manuals, continuing the visual-instruction approach pioneered by cartoonist Will Eisner's wartime Army Motors.

"The Army's 73-year-old comic book that taught generations of Soldiers how to actually maintain their equipment."

PS Magazine taught preventive maintenance through comic strips instead of a dry field manual, because the Army figured out during the Korean War buildup that Soldiers actually read and remembered cartoons in a way they never remembered paragraph-numbered FMs. It came straight out of Will Eisner's WWII-era Army Motors — recurring characters, running gags, a love interest who was always "by the book" — wrapped around genuinely correct torque specs and corrosion-prevention info. It went online-only in 2017 and the Army shut it down for good in September 2024 after seventy-three straight years — proof that boring compliance content and something people actually enjoyed reading were never mutually exclusive, if anyone bothered to try.

The formal name of South Vietnam (1955-1975), used throughout US military orders, unit histories, and official documents of the Vietnam War era to distinguish the US-allied government and territory from North Vietnam (Democratic Republic of Vietnam, DRV).

"The official abbreviation for South Vietnam that shows up throughout Vietnam-era orders and unit records."

RVN shows up constantly once you're reading original Vietnam-era orders and after-action reports instead of popular-history shorthand — it means the Republic of Vietnam, the US-allied government in the south, as distinct from the DRV in the north. Campaign credit, unit lineage, and award citations from the war are written with RVN in the text, so if you're pulling a DD-214 or a unit history from that era, you need to recognize it instantly to make sense of the document. MACV reporting, State Department cables, and Vietnamese-American refugee-resettlement records all use it the same way, which makes it one of the more useful pieces of period vocabulary for genealogical, historical, or benefits research tied to that era.

A section of Arlington National Cemetery that has become the primary burial ground for US service members killed in the post-9/11 wars in Iraq and Afghanistan, administered by the Army under Army Regulation 290-5 alongside the rest of the cemetery, and widely described by visitors, journalists, and cemetery staff as the section where those conflicts' losses are most visibly and recently concentrated.

"Section 60 — the part of Arlington where the wars since 2001 are buried, still being visited by people who knew them."

Nothing marks Section 60 as different on a cemetery map — same rows of white headstones as everywhere else — but without any formal designation, it's become the place where the post-9/11 wars are most visibly present: graves close enough in time that the people visiting are often still active-duty friends and immediate family, not descendants tracing a distant relative. Visitors leave photographs, letters, unit coins, personal items in numbers the cemetery has had to write its own policy to manage. If you served in these wars, or lost someone who did, this section carries a weight that has nothing to do with rank or acronym — a reminder, walking those rows, of exactly what the rest of this glossary is actually about.

An automatic, across-the-board federal spending cut mechanism established by the Budget Control Act of 2011, triggered when discretionary appropriations exceed statutory budget caps, applying a uniform percentage reduction to every program, project, and activity within the affected budget function rather than leaving agencies discretion over where cuts fall.

"Sequestration — the automatic, across-the-board budget-cut mechanism that hits every program the same percentage, whether it makes sense there or not."

Congress built this into the 2011 Budget Control Act as a forcing function nobody actually wanted to trigger — automatic cuts as the deliberately ugly fallback if a broader deficit deal fell through. It fell through. Sequestration hit in 2013, and because it applies a flat percentage across every program in a budget function, a high-priority modernization program gets cut exactly as hard as a low-priority one — no discretion, no protection for what actually matters. Congress has patched the caps repeatedly since, but the fear of the mechanism kicking back in still shapes every defense budget fight.

A Department of Defense youth education program, funded by Congress beginning in Fiscal Year 1993 and administered by the Office of the Assistant Secretary of Defense for Manpower and Reserve Affairs, delivering roughly 25 hours of hands-on science, technology, engineering, arts, and mathematics instruction to primarily fifth-grade students at National Guard, Reserve, and active-duty installations nationwide.

"STARBASE — the program that brings local fifth-graders onto base for hands-on STEM taught by service members."

STARBASE is one of the rarer DoD programs built entirely for civilians who'll never serve — mostly fifth-graders, often from schools underrepresented in STEM, spending about 25 hours doing hands-on science and engineering led by Guard, Reserve, and active-duty personnel on an installation's own equipment. If you're the one running it, it's a real departure from your day job — explaining aerodynamics to a room of ten-year-olds instead of doing your MOS — and the program has grown since its 1993 pilot into dozens of states, with a middle-school follow-on for kids who finish it. Easy to skip past in a glossary full of operational jargon, but it's a real, funded, enduring piece of how DoD engages the communities around its bases — no recruiting pipeline attached.

Per Army food-service doctrine, a semi-perishable, fully-cooked group-feeding ration packaged in half-steam-table-sized rectangular cans (tray packs), introduced in fiscal year 1985 to provide hot meals to larger formations in the field with minimal preparation equipment and personnel — distinct from the individual, self-contained Meal, Ready-to-Eat.

"T-Rations — the "hot chow in the field" option, cooked once at scale instead of packaged one soldier at a time."

A T-rat heats a group-sized portion — chicken and gravy, sausage and eggs — out of a can roughly the size of a steam-table pan, letting a small field-kitchen crew put out an actual hot meal with a fraction of the labor of cooking from scratch. Fielded in 1985 alongside the modern MRE, because constant MRE consumption wears on morale in ways a hot, familiar meal doesn't, even when both hit the same nutrition numbers on paper. The menu cycle got trimmed from fourteen days to ten after testing found nobody noticed the extra variety — a rare case of the Army actually testing an assumption instead of just adding menu items forever. "T-rats tonight" versus "MREs again" is a bigger morale swing than either one gets credit for.

A World War II-era American military slang acronym describing a situation more seriously disorganized or degraded than the everyday-normal chaos implied by SNAFU, part of a shared informal vocabulary (alongside SNAFU and FUBAR) that let troops grade the severity of dysfunction with a kind of ironic precision.

"TARFU — WWII slang for "this is worse than the usual amount of screwed up.""

American troops in World War II ran a three-tier vocabulary for chaos: SNAFU, Situation Normal All Fouled Up, was the everyday baseline; TARFU meant noticeably worse than that; FUBAR, Fouled Up Beyond All Recognition, topped out at total, unrecoverable catastrophe. The term got official enough to star in Army-Navy training and morale films — Seaman Tarfu appeared alongside Private Snafu and Private Fubar, including the 1944 short "Seaman Tarfu in the Navy." SNAFU and FUBAR both escaped into everyday civilian English and are still in use; TARFU never made the jump, and stayed a linguistic fossil, a real piece of the same wartime slang family, occasionally used by veterans and history buffs, but unknown to almost everyone else.

Informal military slang, not a formal acronym, clipped from "interpreter" — referring to a local-national or contracted linguist who translates between US forces and the local population, used constantly during the wars in Iraq and Afghanistan and documented as part of the informal vocabulary that emerged from those deployments.

"Terp — the interpreter every patrol, checkpoint, and key-leader engagement in a foreign country actually depended on."

A terp was rarely just translating words — on patrol, they were often the only person who could read tone and local context well enough to tell you whether an answer was evasive, honest, or dangerous. A good terp kept a unit safer than any piece of gear in the vehicle. And they took real, sustained risk for it: working publicly with US forces marked them and their families as targets long after the deployment ended, which is the entire reason the Special Immigrant Visa programs exist. Troops who used the word constantly will also tell you it's a little dismissive for a job that carried that much danger and got that little recognition. For a lot of veterans, it's inseparable from an unresolved sense of owing something to a specific person who's still waiting, or never made it out.

Informal but institutionally established terminology — first documented in a 1964 program-management paper describing "undomesticated and uninhibited technical specialists" — for a small, cross-functional team of experts assembled outside the normal chain to solve a specific, urgent technical or operational problem, or to test defenses using unconventional, adversarial tactics.

"A tiger team — the group of specialists pulled off their normal jobs and told to fix the one problem that's actually on fire."

The phrase is old enough to be real institutional vocabulary, not just slang — it first shows up in a 1964 program-management paper, describing exactly what it still names: specialists pulled outside the normal chain and told to attack one urgent problem without the usual constraints. Its most famous outing is Apollo 13's mission control team, who improvised the carbon-dioxide fix that got the crew home — a genuinely life-or-death tiger team whose members later got the Presidential Medal of Freedom. The same idea runs through defense work constantly today, from cyber red teams testing a network with deliberately unconventional attacks to engineering teams assembled when a weapon system breaks in a way the normal sustainment chain can't diagnose fast enough. Standing one up is itself a signal — it means leadership already concluded the normal process lost the race against the problem.

Public Law 115-68, enacted 6 October 2017, requiring the Departments of Defense, State, and Homeland Security and the US Agency for International Development to develop and report strategies for promoting the meaningful participation of women in conflict prevention, peace processes, and post-conflict recovery, on the evidence that including women improves the durability of peace agreements and stability operations.

"The WPS Act — the law that makes "get more women into the room during conflict resolution" an actual federal reporting requirement, not a talking point."

Passed with bipartisan support in 2017, built on research showing peace processes with real women's participation hold up measurably better, it makes four federal agencies — not just DoD — publish an actual implementation strategy instead of a values statement. DoD's WPS framework shows up as concrete things you might run into: female engagement teams working alongside infantry in cultures where male troops can't talk to local women directly, gender advisors on operational staffs, training requirements tied to law instead of command discretion. It's less an abstract policy paper than a set of real billets and staff positions that exist because Congress decided the evidence was strong enough to legislate.

Informal military slang, not a doctrinal or formal timekeeping term, referring to an unspecified very-early-morning hour before sunrise — built from the 24-hour military time convention (the "zero" prefix used for hours 0000 through 0900, plus an approximate "thirty" minutes past) — used to describe early PT formations, road marches, wake-up calls, or operations deliberately timed to exploit darkness.

"Not a real time on the clock — just the universal answer to "what time did formation start?""

Zero dark thirty is deliberately vague — could be 0330, could be 0530 — because the real message is "earlier than you wanted to be awake," delivered with the specific dark humor that shows up around chronic sleep deprivation. There's real logic under the joke: darkness hides movement, cooler pre-dawn temps make sense for road marches and PT. Say it in a formation and everyone thinks of wake-up calls, not doctrine — until the phrase went fully mainstream via the 2012 film of the same name, which borrowed operator slang for the pre-dawn timing of the raid that killed Osama bin Laden.
