the silly military

The Army has a PT uniform (outfit to wear when working out).
The Air Force has a PT uniform.
The Navy does not (yet) have a PT uniform.
Some Army people apparently only care about that third point and are seemingly rather upset about the fact we are free to wear whatever we want while working out, so long as it is in good taste and reflects our Navy pride. So I purchased a couple shorts from the good ol' Naval Academy, one blue, one gray, both do not go below the knees, but I am now under the understanding that I can only wear the blue ones. The reason behind this asinine rule is that, while we still do not have a PT uniform, we were issued these silly looking blue shorts that are just plain ridiculous, so while we are at liberty to deviate somewhat we still have to wear blue shorts.
Well, what are they going to do, keep me in Afghanistan for another 8 months?
And another silly point, the Army people salute each other when in PT uniform. It is the strangest thing and one that takes getting used to as I have been saluted a few times, I first was caught off guard but later simply returned the salute. My question is this, how does the Army private in his Army issued PT gear know that the person approaching him from the other side is an Army general in his Army issued PT gear. Isn't he technically supposed to salute the higher ranking officer as he is in his PT gear?
Just plain silly I tell you!
And no, I refuse to wear our silly looking blue shorts!
