The graveyard isn't always permanent. Sometimes the institution kills a job, then a war or a new threat proves it was wrong — and digs the job back up.
Army·Dead 1920 → Reborn 194020 years in the ground
US Tank Corps → Armor Branch
Died 1920 as
Independent Tank Corps
The National Defense Act of 1920 abolished the independent Tank Corps and handed the tanks to the Infantry. Patton and Eisenhower formally protested. They lost.
Reborn 1940 as
Armored Force (Armor branch, 1950)
The German blitzkrieg through France in May–June 1940 made the case the Army had refused to hear for 20 years. The Armored Force stood up 10 July 1940.
Eisenhower spent the interwar years writing tank doctrine the Army wouldn't read. When France fell in six weeks, they finally read it. The branch Patton was exiled from in 1920 made him a legend by 1944.

BoilermakerBR
Died 1928 as
Boilermaker rating (first death)
The interwar Navy consolidated the rating away in 1928 — peacetime didn't need a dedicated boiler-builder.
Reborn 1943 as
Boilermaker rating (wartime reinstatement)
WWII needed every man who could swing a rivet hammer in a fire room. The rating was resurrected in 1943, then killed for good in 1948 when it merged into Boilerman.
A rating that died, came back for the biggest war in history, and then died again five years later — the rare MOS with two graves and one resurrection in between.
Army·Dead 1973 → Reborn 19763 years in the ground
Chemical Corps
Died 1973 as
Chemical Warfare Service / Chemical Corps
Disbanded 11 January 1973 amid Vietnam-era backlash against chemical weapons and the Agent Orange association.
Reborn 1976 as
US Army Chemical Corps (reactivated)
Soviet chemical-warfare capability made the branch look indispensable again. Reactivated in 1976 — dead for barely three years.
The shortest exile in this list. The Army killed its chemical branch for political reasons, then quietly rebuilt it the moment the Soviet threat assessment landed on the right desk. It still exists today.
Marine Corps·Dead 1944 → Reborn 201470 years in the ground
Marine Raiders
Died 1944 as
WWII Raider Battalions (Edson's / Carlson's)
Disbanded 1944 by senior Marine officers who opposed "an elite within the elite," and to feed bodies to the 4th and 5th Marine Divisions.
Reborn 2014 as
Marine Raider Regiment (MARSOC)
The post-9/11 special-operations demand resurrected the name. MARSOC components were redesignated Marine Raiders in 2014 — 70 years after the originals stood down.
The longest gap on this list: seven decades. The "Gung Ho" motto that Carlson's Raiders coined in 1942 outlived the unit by 70 years and then got its name back.
Navy·Dead 2007 → Reborn 201912 years in the ground
Torpedoman's MateTM
Died 2007 as
Torpedoman's Mate (surface), merged into Gunner's Mate
Disestablished on submarines in 1995 and on surface ships 1 October 2007 — duties scattered into Gunner's Mate and Machinist's Mate (Weapons).
Reborn 2019 as
Torpedoman's Mate (reinstated rating)
NAVADMIN 225/19 brought it back on 30 September 2019 under the Sailor 2025 rating-modernization push. About 1,100 sailors got their TM crow back.
The reinstatement memo explicitly cited "heritage and pride" — not capability — as the reason. The Navy is famously slow to change; this is the rare case where it changed *back*.
Marine Corps·Dead 1997 → Reborn 202225 years in the ground
Marine Medium-Range Air Defense
Died 1997 as
HAWK / Light Anti-Aircraft Missile (LAAM) Battalions
Post-Cold-War "we own the sky" thinking. 1st LAAM Battalion decommissioned 11 July 1997; the Corps bet Navy/Air Force air dominance made organic medium SAMs redundant.
Reborn 2022 as
3d Littoral Anti-Air Battalion (3d LAAB)
Chinese cruise-missile and drone proliferation made the 1990s divestment look like a mistake. 3d LAAB stood up in 2022 — though with Stingers and MADIS, not the medium-range HAWK coverage that was thrown away.
A 25-year lesson in regret. The capability came back, but not the range — the new battalion can't reach as far as the one the Corps deleted in 1997.
