2. M-16s with 20-round mags/M-4s wtih 30-round mags.
I think that's about it... (Oh, and smoking is no longer politically correct, so therefore would never show up in a released photo today).
Yeah, those 20-round magazines still bogle my mind considering the bad guys were packing 30s. One of my co-workers daddy was involved in Southern California's aircraft industry and he managed to send us a box of 30s so that at least our pointmen had them. The only other ones I came across were owned by Special Forces and their indigenous hired help. Apparently there was a bit of a mixed up and a couple of dozen found their way into our rucksacks, but, hey, what the hell, we were mostly on the same team.
Toss in a hundredweight or so of calcium carbide, a few hundred gallons of water, cover it with something for half an hour. Toss in a flashbang or similar. Watch everything jump as the tunnel network blows.
I used to cave and we used Carbide Lamps when I was active (all my friends use LED headlamps now). One guy wrapped his spent carbide bag a little to tight and about an hour later it ruptured creating a cloud of acetylene around him. The open flame of his lamp did the rest. The party had to exit the cave and the poor sod looked a bit worse for the wear. if you're too close to the hole when it goes up, it mighta bit rough on the poor sod tossing in teh flash bang.
I would like to watch teh tunnels go up, though.
