From Reuters, President Obama passed his first test with the military today-
Note the straight arm and wrist, the correct angle, and just the right amount of deflection on the hand in relation to the head.
The man in the middle is Chief of Naval Operations Admiral Roughead. The man on the right is Vice President Joe Biden, who for some crazy reason has his hand over his heart. Actually, he's correct in doing so, because the VP is not in the chain of command, hence he is not saluted by soldiers in uniform.
Bravo, Mr President.
