These spots are useless as it's easy mode for the first few round's were these spot's in the truck's only really work
you will get to the later rounds faster running around killing them rather then laying prone in a truck picking them off + it's boring as hell 2 do it's more fun rushing them
As soon as the later rounds come your screwed as the truck will easily explode with the C4 Dog's Jugg's and The Heli's etc
and when it does explode you can't jump in it again. rendering these spots absolutely useless IMO
