Alright this is a slight varation of the bunker i normally make, i took about 20 mins to build by my lonesome(thats mainly cause i've gotta have strait edges and other perfectionest crap) i could be part of a forward bunker or even could be made to be just part of the wall
looks good but kind of impractical when dealing w/ a time limit.
i think if u made the bottom window a little smaller it'd be way cooler cuz then if u were getting shot from upper u could just drop down and peak lower real quickly to surprise them
