I have a soldier with an ETS date is in 20 days, and the command wants to give him a PT test. Does the soldier have to do it/pass or fail?

He's still in the military until he isn't... if they give him a lawful order he is obligated to obey it... end of story!!!

As long has he did his phase out physical (phase 2 or 3 don’t remember which) he is exempt from PT and PT tests

Like it or not, he is still a soldier..for at least 20 more days.
If I were him I would take it. Whether he passes it or not is irrelevant, he did the PT test, as ordered.

When I was a Squad Leader(SSG/E6) I had a Soldier to complete his phase 2 physical exam for separation from the military. On all official documentation he is a loss and a Soldier has been requisitioned to take his place. At PT formation we began to conduct warmups and this Soldier, while jogging in place, steps on his keys and we all could hear the Pop. The Soldier broke his foot stepping on the keys. Fast forward. 9AM I am explaining to the Company Commander and 1SG what happened and why the Soldier was participating in PT after having completed the phase 2 of his separation physical exam. Because the Soldier was close to getting out of the Army all communication was face to face all the way to 18th ABN Corps HQ. I forgot to mention that I was in the 101st Chemical Company on Fort Bragg. Before the day was over, it was explained to me in great detail, that the military will have to pay the Soldier beyond is ETS date because the Soldier has to be extended for medical reasons. The Soldier will receive medical care until he is fit to leave the military. And I was told that I should have used common sense and have the profile PT instructor to take charge of the Soldier. For the remainder of my career I never made that mistake again while educating the NCOs on my team. Many years ago I had a SGM to tell me that there is a fine line between being hard and being stupid. You decide which side of that line to be on.

My suggestion is go thru your chain of command to resolve this issue and not this site. See what they have to say, then you covered your ass.

Does your commander, Battalion or Brigade know this is being required by a company commander, current DA level orders have waived the APFT from 1 October because of the new APFT transition. Current test is good through 1 OCT 2021(FY). There is no regulation, however, that exempts a Soldier from ANY PT or test until they sign out regardless of ETS/Ret physical complete.

As I was ready to retire, I rejected the Air Force desire to give me a 10% disability. I was looking forward to entering the private sector and stare a civilian career. That worked for me real well for more than 10 years, then I had a heart attack and required medication on a daily basis. Not a problem initially, and then I deployed to Miami for Hurricane Andrew. I ran short of medication and visited the VA to see if I could refill my medication. They could not find me in their records, but did check me out and provided me with a two week supply. After that, my local VA in Atlanta asked me to come in for a check-up. They found that I was suffering from type II diabetes, caused by Agent Orange and granted me a 40% disability. I asked them about the heart attack, and they said that Agent Orange had nothing to do with that. By that time, I had already suffered, or survived three heart attacks. A young Solider, suffering with the same condition I had with my heart, challenged the VA's finding and won his case. The VA called me in based on the legal finding and reviewed my history and decided to grant me 100% disability. However they were only willing to go back to my first visit, some 10+ years to pay me the disability pay. I loss more than 10 years of pay. I say all of this to suggest, if the military want to check you out before leaving, accept it. Get it on record, it may pay off in the future. Just an old man's view.

The bottom line is the unit is going to do what ever they can get away with. If a challenge is presented then plans change miraculously. You as soldiers leader should be fighting to allow soldier ample time not having to deam with this b.s. if need be take the hit. I can only speak for myself a soldier who has done physicals will not be going to field or take pt test. His focus should be on ensuring he has something set up for future success not about whats going to be in his past

Of course the commander is going to require it. That's the commander's job/discretion. In good faith, even though the SM is getting out, should take the APFT. If the CO wanted to make it worse, he/she could pursue UCMJ action and delay SM's ETS.

One of the companies I support had a SM do a 12 mile ruck the day before he ETS'd. The kid was literally signing out the next day. I wish I knew about this so I could train that command team.
