You will salute in uniform. Is the PT uniform not a UNIFORM?? I always have saluted, if not ENGAGED in PT while in PT's.
Where are you MSG Smith that you don't salute the flag in the morning at FLAG CALL. I have been in several posts, for different reasons and let me tell you get cause simply walking through flag call with out rendering the proper customs and courtesies, AR 600-25 (below is straight from this site)
What are the courtesies rendered by individuals during Reveille if they are in uniform and not in formation either with or without headgear?
1. At the first note of music, face flag and render hand salute (if flag is not in view, face direction of music).
2. End salute on last note of music.
What are the courtesies rendered by individuals during Retreat and To the Color if they are in uniform and in formation either with or without headgear?
1. At the first note of Retreat, execute "Parade Rest" at the command of the officer or NCO in charge. Remain at Parade Rest until given "Attention" by officer or NCO in charge.
2. At the first note of To the Color, execute "Present Arms" at the command of officer or NCO in charge. Execute "Order Arms" at the command of officer or NCO in charge.
What are the courtesies rendered by individuals during Retreat and To the Color if they are in uniform and not in formation either with or without headgear?
1. At the first note of Retreat, face flag and stand at attention (if flag is not in view, face direction of music). Remain at attention until last note of "TO THE COLOR" has been played.
2. At the first note of To the Color: If outdoors, render hand salute; if indoors, stand at attention. Hold this position until the last note of music has been played.
Ok so it does not say in the PT Uniform but I have always seen PT start after Reveille and it is a company formation and YOU DO SALUTE THE FLAG!! I have not been to every post in the Army, not even close but I have seen what happens if you do not salute. Heck you can even get in trouble if caught driving, with loud music so that you can't hear flag call. Not good, honor the American Flag!! It takes a few minutes out of your day, personally deal with it, we fight for it everyday, we have faught for it over the years, give it the respect it is due, but that's my opinion. If I disrespect you with that opinion I am sincerely sorry, but it's again an opinion.
The average Shepard can run 35mph, can you??
