The scavengers are a class of enemy that sprint around the battlefields of the game, stealing the games currency, intel. Usually lightly armed, they prefer to stay away from major engagements.
It seems that the battle bosses of the game also have the ability to take intel. The Widower, when she has taken a great deeal of damage, will use a jetpack system to fly into the air, out o0f the battlefield. When this happens, all intel nearby is taken by her. Other examples include General Okoro, who can be seen taking any and all intel from the Pirate Bay as he runs away from The Operative along a boardwalk.
