Military units may employ new or special weapons within a unit to supplement the abilities of other weapons if it can do things current weaponry cannot. For instance, it would be great to equip every trooper with rocket launcher but the weight and ammunition requirements make it impractical. It would also be too dangerous in close quarters like house to house, or room to room fighting. Here is a list of different weapons, most of which are not available today. Like a squirt gun this expels acid at the target.
Acid can be either a chemical acid or nano-bot destroyers.
It would be very similar to a flame thrower. A weapon that uses the magnetic field to 'arc' an energy beam onto an enemy that is hidden from direct view. A generic term for a weapon that shoots a beam of energy. A generic space opera weapon with various effects. A different kind of blaster.
