1. Incendiary
   Concussion
2. Practice
   Blast

An incendiary grenade is intended to cause a huge fire, like the AN/M14. It's also known as a thermite grenade, as it releases molten iron when it explodes. It can actually explode underwater as well, and it's used more to destroy equipment.

   Pickaxe
2. Folding hook
   Entrenching tool

Military entrenching tools may be for digging, but they are recognized as weapons, too. In fact, the M-1943 tool's folding "spike" makes it an effective hand-to-hand weapon as well. Some military forces around the world train their soldiers on how to properly use entrenching equipment as weapons.

1. Single-action
   Automatic
2. Revolver
   Derringer
