Using my desk-top buddies as inspiration, I am building an elite group of four inch high miniature soldiers, created to be air-dropped into a situation of dire danger to perform feats of daring espionage and destruction....
The first task I have is how to arm these guys to enable them to go into battle. Obviously, scaling down real-world assault rifles just won't work for a variety of reasons (small projectiles, big air resistance).
So, what can I arm these guys with to give them some effectiveness when infiltrating and dealing with human scale installations and enemies?
Background: These are living, breathing miniature men, scaled down to roughly 4 inches high. They are not overly strong or have special abilities. The illustration above is only my inspiration. The method of the guys creation/miniaturization is outside the scope of this question.
Intended mission profile: I have a strike force of 100 of these guys that I airlift within reach of their target from a drone and then airlift them back out again in the same way. They're the ultimate in stealth attack.
