Bragg was very unpopular in the AoT for quite a number of good reasons. Among them was his orders against firing weapons except upon orders, and he specifically outlawed hunting for food. With the AoT starving (even while attempting to beseige Rosecrans at Chattanooga), soldiers were especially bitter at being unable to send out hunting parties to bring in wild game.
Bragg's order wasn't because he wanted to conserve ammunition, he just wanted to keep gunfire to a minimum so that officers could hear the warning shots of a picket's rifle, or the sounds of an attack in progress by the enemy. A reasonable basis for the rule, but one which still didn't sit well with the empty bellies of the Confederate soldiers.
Given today's preoccupation with losing weight, I've often toyed with the idea of marketing "The Confederate Diet", a sure-fire way to lose those extra pounds. It requires the dieter to limit his consumption to a quarter-pound of salt pork and a hardtack bisquit every other day, along with an handful or two of peanuts, and an exercise program which requires the buyer to hike ten miles every day followed by digging a trench with a bayonette and tin cup in their back yard, then filling it in and doing it all over again the next day. Oh, and don't forget cutting wood for fires every day, etc. Buyers who follow the program for six months or so are guaranteed to be called "tawney" by their friends, just as Confederate soldiers were described by Union soldiers in the latter half of the war.
