Remove tanks from squad deathmatch

I had the same realization when I started to complete the challenges for squad deathmatch. On the other hand I also understand why the LAV makes sense to have been included. It's basically for the 3rd or 4th place teams, to try and get more points or to collapse buildings and make the "rats" flee their hiding spots. 

Rather than removing the LAV why not just give it limited ammo that way players actually have to aim/focus on accuracy, instead of just spamming shots everywhere.
