If I'm being separated for unsatisfactory performance (failing two PT tests), does being diagnosed with asthma cancel the separation process?

No it will not stop your separation due to the fact even with asthma you either get a no run profile or no profile at all and without a profile you are still expected to pass your 2 mile run. And if you do receive a no run profile you will be separated for the asthma.

Talk to legal. Chapters for APFT failure is Honorable.

Was your asthma documented in your military records any time PRIOR to these APFT failures? Is this exercise induced asthma or a constant issue where you're hitting a puffer at random moments? Did you get treated at your OSUT TMC for your breathing problems?

Honestly, at this stage of the game, you might want to start packing things.

I'm surprised you didn't notice you had trouble breathing during normal PT or when you were preparing for your PT test. Especially your second failure. Might have asthma? Sounds to me that more than likely you are just out of shape.

Shaking my head here...Asthma creeps up on you, not boom! next day you have it. How were your previous scores? If you were near the fail line on the runs then Yes, you might have a breathing problem. IS there any thing else that might be a contributor? Different area with allergen in the air? How often do you PT (BETTER BE 3 TIMES A WEEK) any less than that and you might just need remedial PT. Good luck with delaying your discharge, if you do in fact have Asthma then you will most likely be at end of service life. Semper Fi.

This is from the Army Trial Defense Service:

"5. TYPE OF DISCHARGE : Soldiers separated under this program will generally be given either an honorable discharge or a general under honorable conditions discharge (Para. 13-10, AR 635-200). a. HONORABLE: This is a separation with honor. An honorable discharge will be given for proper military behavior and proficient performance of duty. If the soldier has served faithfully and performed to the best of his ability, and there is no derogatory information in his military record, he should receive an honorable discharge. If there arc infractions of discipline, the seriousness and frequency will be evaluated. When there is a doubt, it should be resolved in favor of an honorable discharge. An honorable discharge is required if the government introduces limited use evidence (see Para. 3-8 (a) and (g), AR 635-200). b. GENERAL: This is a discharge under honorable conditions, soldier whose record and performance is satisfactory. This is usually given to someone who had non-judicial punishments (Article 15s), but not for serious infractions. When this type of discharge is given, the commander must state the specific basis for it. c. UNDER OTHER THAN HONORABLE CONDITIONS: This is a discharge issue ordinarily for misconduct, fraudulent entry, security reasons, or for the good of the service. This discharge carries considerable stigma and deprives the soldier of substantially all veteran’s benefits accrued during the enlistment period. This type of discharge is usually not given under Chapter 13. "
