A marine drill sergeant fancied a game of golf one afternoon and so set off to play on his favourite course. Waiting on the first tee, he noticed an air force commander, and since both were alone and in the armed forces, they decided to play together. They soon started talking about work. They shared boot camp stories, war memories and jokes about new recruits. They carried on like this until the fifth hole, when the marine sergeant concluded a story about a runaway tank by saying: "It's a fact that the marines are the bravest of all the armed forces." The air force commander dropped his putter. "What do you mean by that?" he demanded. "Well," the sergeant went on, "who do you send to take new territory? Who do you send in when you're outnumbered? Who gets the call for the most covert operations?" The air force commander putted out before snapping back: "While you lot are hiding in the bushes, who is a clear target in the sky? Who do you call for support when you're losing? No, sir, the men of the air force are the bravest." This argument lasted for the rest of the round, with both men insisting that their men were the bravest and producing stories of outstanding bravery to back up their claims. After finishing, they headed up to the clubhouse for a beer, still debating the matter. Finally the marine sergeant said: "I must get back to camp. Do you want to play again next week?" Hearing this, the air force commander said: "I must apologize, it seems I was mistaken. Anyone who played like you did today and is willing to come back to the same golf course is a much braver man than me!"
