Bot and technical issues

I notice tanks will appear in random spots when one was not there then it kills me. I never had the opportunity to see it. Sometimes when you destroy one tank another appear behind it. The tanks should arrive in the distance or at some other point not appearing before me on the consistent basis.

When you shoot a bot, all of a sudden a bot appears next to you in a blind spot and kills you. You do not have a chance of seeing these bots. We need the opportunity to see the bots approaching. 

The snipers have a great advantage on this game. I have not made it far in the game yet but it would be nice to send a helicopter strike (multiple bombs) at the sniper

I would like to see a neck snap / choke hold instead of stabbing a guy for dog chains.
