Oh man that would be amazing. I would love if you could just straight up build bunkers and little defense positions anywhere on the battlefields. The only reason I think it would be unlikely is because maybe the game can't handle it?
Since certain stuff lags out the game, like if bodies didn't dissapear (btw if bodies stick around for a while, leaving huge heaps of dead bodies everywhere I would f'ing love it) the game can sometimes lag out from all the excess stuff floating around. Hopefully they have a setting or something so if your computer is good enough you can make it so the bodies, bullet holes, missle craters and all that stuff stays around during battle.
That would make a really cool support class, or little side tree or something. The ability to set up certain things. Maybe at first you can only set up a few sandbags that only protect you from machinegun fire and you have to stay prone behind it to get good cover out of it. But then you can get more so you can make bigger and better stuff.
I'm probably dreaming and I really don't want to get my hopes up. But wow that would be amazing
