The J-97 Mosquito is a handheld particle weapon in the shape of a derringer. It was once used to test out how small energy-based firearms could be scaled down hence its name. A small power cell allows the device to fire off a bolt of highly charged particles with tremendous destructive potential. Whatever the bolt hits will receive roughly the same amount of damage as two shots from a Siege Tank. This is usually enough to take down any armored infantry unit.
