i agree with the last guy
it sounds a lot like M.A.S.H. with the guitar even though its not the same key and it doesnt follow the exact tune its the first thing that pops into my head... it reminds me of someone walking around a small military installment and showing off the different rooms like the infermary and the bunk house and the mess hall then in the middle of the song someone comes in in the middle of the night trying to kill the soldiers and you hear what sounds like planes overhead. then the next day comes and everyone is assesing the damge and trying to get over the deaths of their comrads eventually fading into everyone returning to their posts and resumeing normal duty.
