Time was running out... it was almost dark and they had to leave the prison now. They needed to group up and spread out to hope to find a way out. Now who are you?

(Note: Prisoners are all dressed in regular cloths

Guards wear a suit of body armor. Have a shirt, pants, and underwear on under the armor but shoes could not fit so they just wear the armor boots. (Remember no nudity) They also carry a machine gun, knife, and torches that when striked, light up on fire.

Ammo for gun which you can find (You can come up with more):

Flame Thrower: Sets things on fire, good for plants.
Shot Gun shells: Close range but good against animals and giant insects. )
