The more I look at that Sailor's Rating Badge, the more I tell myself he's a 2nd or 3rd Class Machinist's Mate (compare to the 2nd Class MM seen on the left here. It's hard to tell, but he may have 2 chevrons, not 1. He's also got a hashmark further down his sleeve, denoting at least 4 years of service (but less than 8, obviously).

Looks like a 3rd Class Petty Officer of some rating behind them with an ammunition belt of the type to be worn when on duty. I am sure he is there to keep the Georgia Tech fans off the field, after Navy's crushing defeat of Georgia Tech 13-0.

These two wouldn't stand a chance against a Newsie or Coal Mine Boy.

The kid on the left has something that looks like string around one finger.

Wonder if he's supposed to remember something?

After looking at this picture for three full days without a single solitary comment being posted, I can only believe we old crones have become cynical regarding cute but precocious kids posing as adults (who can get obnoxious if they are not one's own). However, since I am mystified by photos on Shorpy without commentary, I am compelled to say " how adorable". After all, they were obviously somebody's darlings, even if they don't personally appeal to some of us, even though they may appear to be spoiled rotten. They just better stay out of my yard.
