Delta, on ammo, you are spot on! On body armor, however, you omit a really salient fact; regardless of protection level, none I have seen offer any head protection. Advantage goes, as it has since the origin, to the skilled operator, especially if he gets the first, unexpected, shot! Tactics, always, tactics! Given the advantage of superior position (I planned this ambush) a Ruger #1 in say, 7 Mag, trumps a squad of m-4's, every time, with much less logistics, since I chose my battle! I was trained as an 'unconventional warrior', many years ago, and seem to have never lost the mindset. Fidel Castro came to power against the Battista regime using leverguns, whiskey bottles, and mogas; the others had tanks, yet Castro came out on top-figger that? Pick your battle-fade, rapidly, from an unsatisfactory position, and re-join only on your terms. Pick, or create, a battle situation, that favors your ordinance, and you win. I never counted on tac-air, as reliable, and so, always created my situations as to be win-able, without them; ditto, the big stuff from the sp155's. Given the jobs I usually caught, and the places I had to play in, the fact that we're corresponding, tonight, supports my theory pretty well, I think.
