500 calories deficit for 1lb of weight loss per week is more or less correct. But the deficit depends on calorie expenditure, not only on intake. Most combat rations nowadays contain from 3500 to 4000+ calories per day, not 2500. Royal Navy sailors used to consume 4000-5000 calories per day. I'm quite convinced that around 3500 was probably required for non-combat troops, 4500 for combat troops in those conditions. Though people were a bit shorter back then, so I don't really know. That's what it takes to fuel an average soldier nowadays.

@heespeseth You are wrong. That simple. Spec-ops on garrison duty - not in combat - I stress it! "The current USARIEM study began at the Combat Diver Qualification Course in Key West, Fla. Crombie said preliminary results indicate that service members at that venue needed 4,600 calories a day. " As contrasted with regular soldiers, who need less. "NATICK, Mass. (Jan. 24, 2013) -- A typical service member in garrison needs to consume about 3,250 calories a day for sustenance. " "The MDRIs for calories can meet the needs of the average Army personnel. Men and women should have 3,250 to 4,600 and 2,300 to 3,150 calories, respectively, per day, which will fluctuate based on size. The Departments of the Navy, Air Force and Army say the daily calorie requirements are based on a 174-pound, 69-inch man and a 136-pound, 64-inch woman. " 3500 in combat is a starvation level diet. That's acceptable for a short period of time, especially if you have to carry all of those extra calories on your back. It's not sustainable, though. You need about 5K for that. "The RN was and is stil on an unhealthy diet :)" I beg to disagree. If they ate 2000 cal surplus, which is what you seem to claim, they would look like whales. Study the paintings from the period. Those guys were wiry! (Apart from the higher ranks, who ate better and worked much less.)
