This footage, which appears to show civilian contractors, has a small convoy in contact with an enemy element. They return fire with everything they've got to not be overrun.

In a convoy of barely armored vehicles, speed is security. When you can't be fast, you have to be violent. This video shows exactly that. A group of contractors finds themselves in an ambush. They aren't able to directly push through the contact, so they dismount and repel the enemy attack through violence of action.
