Only been 52 years since I was in a mortar pit! Too late now, but the flash will show up at midnight like a roman candle. The pits we had at A102 had to been six or maybe even eight feet deep. Every one was made different, so your just fine. Still you can trust me when I tell you it so dark out there, that you can spot the end of a cigarette at 200 meters. Your ammo storage is just fine. We had a bunker just outside the pit that was about eight feet deep as well. You almost always start with illumination, and then move to HE, and once the illumination goes off they start looking for the source real hard. Our pit was a figure eight shape with four tubes. One 4.2" and the Russian counterpart. The other had an 81mm and an 82mm in it. SF had an almost endless supply of Chicom and Russian ammo, so why not use it up!
