A script to make soldiers get fallen enemies guns?

[eagle-eye]

Could someone point out how the following is done?

Group of rebel soldiers with poor armament attack enemy, and when there are dead enemies as a result, they go and get enemy guns, binoculars, pistols etc and then run away to a certain location.

Player would be the team leader and it would be easier when not needing to assign men to take enemy guns all the time.
