The Ming's 32 roket arrow shooters named "Bees," released from a large battery, or the "Nest."
The Russian rocket grenade blaster easily called the RPG-7 that is dead accurate.
Pros: Having much more projectiles that might hit and kill. Used in teams so higher chances of killing.
Cons: Hardly any accuracy at all. Hard to transport and not so portable.
Pros: Great accuracy. Can kill many people in a group with still having accuracy.
Cons: Very slow in reloading. Can deactivate and be a dud.
Edge: RPG = Even if 32 arrows are blasting at you and can kill, say two out of eight, you could take great aim and kill all the Ming in a second.
