It would be nice with the new changes to the GV's to add a little more realism; camo netting and the ability to dig in.
It might work something like this: Each tank/vehicle is equiped with the ability to do one or the other once per sortie. Once employed it takes a set amount of time, maybe 5 minutes to complete during which time the tank is vulnerable as the crew is busy employing this. If danger approaches the employment can be aborted and the crew returns to positions but the one use is gone.
Once employed the camo net takes on the look of whatever terrain it's on although without 100% coverage. I know that there's no level below ground to dig into so rather than digging the crew trows up a berm around the tank creating a hull down position.
Just a rough idea.
