M203

The M203 is a single-shot, 40mm grenade launcher that attaches to many Rifles, but was originally designed for the U.S. M16 family of Rifles, including the M4A1 and the HK416 Carbines.

Battlefield: Bad Company


In Battlefield: Bad Company, all assault rifles are equipped with a grenade launcher that shoots 40mm grenades. They can be effective and deadly in singleplayer, but in multiplayer, it can be difficult to actually achieve a kill as it will merely severely damage an enemy, even a direct hit.

Grenade launchers are very effective for destroying objects, anything from sheet metal fences to concrete walls, but it very ineffective against heavily armored vehicles. A player is always required to pull out the leaf sights for the grenade launcher to fire the weapon.

Battlefield: Bad Company 2
In singleplayer, all assault rifles are equipped with a 40mm grenade launcher, being either the GP-25/30, GL1 or the XM320.

In multiplayer, they act similarly to the original Battlefield: Bad Company, only that it has an increased damage making it much more effective. It is also unlocked as soon as a player begins playing multiplayer. It can be replaced by a 40mm smoke grenade launcher or a 40mm shotgun. Its damage and blast radius can be increased by the Improved Demolitions Specialization.

Trivia

 * The 40mm grenade launcher in Battlefield: Bad Company 2 counts as a separate weapon from the rifle it is attached to. Its skill level can be upgraded separately.
 * A good strategy for the Attackers in Rush is to bombard the M-COM building's walls with the 40mm, causing the building to collapse and destroy the M-COM Station.
 * The grenade launcher is commonly referred to as the "Noob Tube" by online players because it has a history of being relatively easy for players to get kills while requiring little skill to aim in other FPS games. However, in Battlefield: Bad Company the grenade launcher is reasonably hard to gain a kill with. This is not the case in Battlefield: Bad Company 2, as kills can even be attained through walls by destroying them.
 * In Battlefield: Bad Company 2, the M203 is the only under-barrel grenade launcher that cannot be found in singleplayer.
