Rogue Spear[]

The 7.62mm 21E3 LMG is a weapon featured in the Tom Clancy's Rainbow Six: Rogue Spear Urban Operations expansion pack.

Based on the 7.62 G3A3 framework, the 7.62mm 21E3 LMG is a light machine gun firing the 7.62x51mm round from a 100 round box magazine. This round packs more punch than the 5.56x45mm round. In addition, the 7.62mm 21E3 LMG has a single shot and three round burst option. It is more accurate than the M249 SAW, but is harder to control when moving around. As with the 5.56 M249 LMG, this weapon is best used from a stable firing stance.
