Everyone will know that guys on vehicle coming from rear side. Because of their rapid firing rate, sometimes they are uber-deadly, even more than snipers. Thus, I decided to use halftrack, and it worked quite well! For most of the times, I can turn them into scrap metal and make mincemeat pie with its crewmen without damaging my soldiers by concentrating fire.
I think that you guys have your own idea to cope with them..
