SPOILER:
The two jeeps transport the escape detainees to a location for helo pickup. A MI-24 comes in and picks up the detainees, you are given orders not to fire on the helo and to keep distance. You follow the helo to the location for intel (for bigger fish to fry in future missions). A UAV marks the helo with IR designation the entire flight to help keep tabs on the fast helo. Once the helo lands, and coordinates received, you are given the green light to destroy the awaiting troops, MI-24, and escaped detainees. Pretty cool ending, with credits, etc. RTB to Kutaisi.
