I'd be concerned about turrents and mines along the A.I.s preset path of travel. Once people learn the routes for the A.I. you can expect both during your escort.
That's assuming the AI are programmed to use preset routes instead of being given the ability to adapt to enemy tactics (which is a distinct possibility).
There is not preset AI path. The AI is situationally adaptive.
This they use SMART and will likely be more adaptable than many players early on.
8 fatties with 8 miniguns and 8 turrets would be, firstly, hilarious and secondly, only an unbeatable team if you kept throwing yourself at them without changing tactics: sniping, using operatives, grenades, EMPs, flanking, etc.
What team has 8 engies anyway?
