Stinger

 is a gun that fires rockets which explode into bees. Three bees are shot together with every rocket and when a rocket explodes, it creates 5 more bees.

Trivia

 * The gun is based on the real-life rocket launcher of the same name. The Stinger's ability to generate bees is an obvious pun on its name.
 * The Description of the gun may be a reference to the first fight against Liquid Snake in Metal Gear Solid.
 * "Drone Warfare" may be a reference to the fact that male worker bees are called "drones".
