hey here is some basic information about the OICW:
OICW
stands for Objective Individual Combat Weapon 0_o!
It has a 20mm grenade launcher fully attached with a laser-sighting that can be adjusted, and automatically used since its electronic system calculates the distance your aiming at by its scope. It has 7.62 x 30 (this may be incorrect) bullets. It's scope can zoom up to 20x (or 40x :S!). It still is the best and most advanced weapon in the US army.
Theres more! Shit I forgot the rest!
Hope that helped
