The Shellmet is a community-created cosmetic item for the Soldier. It is a green American M-1 military helmet similar to those distributed and worn during the Vietnam war. There is a black band wrapped around the helmet holding three Shotgun shells and gun oil on each side. When worn, the Soldier also holds a cigarette in his mouth with the "Genteel Smoke" particle effect.
- The Shellmet was added to the game.
- Helmets often seen in Vietnam had a green camo pattern, and many soldiers would strap items on top for easy access, such as the ammo and gun oil bottle shown on this cosmetic.
- Given the notorious gun jamming issues of the Vietnam War, gun oil bottles were common helmet band items.
- Smoking was common during wartime as a way to relieve stress from battle.
- Because they do not share an equip region with this item, the Soldier's Stogie or Soldier's Sparkplug can be worn with this item, letting the Soldier smoke two things at the same time.
