At what rank should Soldiers be exempt from organized PT?

NONE!

Nobody is important enough to be completely exempt from organizational PT. I will admit I never saw, or participated in an organizational run larger than a brigade (1st Bde 3AD, once) but that doesn't mean division headquarters doesn't PT, they are after all a company. I have even seen more than one general officer 'show up' at a subordinate unit to participate in PT. So I have to agree with SSG Fleming, when you append Ret. to your signature block, you are exempt from organized PT.

I am 72 years young. Don't ever give up P.T. at any age or rank . Pvt. to 4 star must be fit at all times .

Never. Even flag officers and their CSMs have a HHC and should do PT with the Soldiers as often as operationally possible. Lead by example and show that everyone does PT regardless of rank and are held to the same standard.

Organized PT maintains "Esprit De Corps." I will always be of the old school that every swinging Richard should fall out for unit PT. Now some of the PT studs will argue that they scored a 300 or a 290 and above so they have earned the right to do individual PT. My response would be a 300 is what you strive for, not just the passing grade for your age group. So with that why should you be "rewarded" for doing what you should be doing anyway? You want to stand out? Help that chubby fat ass work out, lose weight and raise their score 50 points or more. You will feel better about yourself. Now I'm waiting for the 300 club to start whining so let the crying begin. HOOOOOOAH!!!!!

Exempt? How about O-9 and higher, or with a temporary medical waiver. Certainly all field grades need to meet fitness standards, along with every senior NCO. And I'm sure when you said soldier, you meant the question to apply to sailors, Marines and airmen too.

Here's another story. I'm an E4 infantry soldier and we run PT, 5 mile run. We have a guest Reserve First Sargent who sets the pace and he SETS the pace. We are able to keep up, barely. We end the run and he sits down at a picnic table. And then he takes off one of his legs. Then he takes off the other leg. He lost both of his legs below the knee to a land mine in Nam. Nobody should be exempt from OT, nobody.

You take your pack off when you walk out the door. Until that time you still perform at your fullest.

No rank

NEVER - PT is important and everyone must participate.
Oorah !
