Well obviously you cant do all that, as I said the result in 30 minutes of work is a lot better than the one after just three minutes. However what you can do is:
Drive the vehicle off road, shut off the engine, take two nets net out from turret stowage, spread one net over the front of the turret and over the gun and one net over the back of the turret, and back of the hull and maybe even even find a birch or two to lift the net off the vehicle at some points
