use car turrets as covering element

Yeagh I used to do that on multiplayer on some maps. I would roll up with APC or other vehicle on high ground. Infantry controlled by other person would clear town or objective and I would smash enemy from a distance or give commentry on whats going on. Once objective was complete infantry will load up and then move on to next objective. Win win!

Hey any tips for starting off? I seem to have like 4 guys versus a platoon plus of enemy all the time who attack me from all angles. I usually do ok in first battle when we have full ammo but then after when my dudes get low on ammo we get rolled.
