I failed weight and tape but I pass my pt test with 280 and up every time. What will happen to me?

I was 6 foot 5 inches back in the day and could only weigh about 223-225 while I served. So you must easily be between 7 to 8 feet tall.

Unfortunately it’s not all about passing PT, but professional appearance in uniform.

Start working those neck muscles.

What was your percentage? Your age?

You'll be flagged for height and weight, but not APFT. At least you're relatively fit enough to work it off. The APFT hasn't been a good standard of fitness since they adjusted it (made it significantly easier to score high) in early 2000. When I joined a max score was 82 pushups, 92 sit-ups, and 11:54 run.

AR 600-9 has the answer you’re looking for!

Flagged, counseled, etc., then:
COA 1. You lose body fat (weight) and make progress in the ABCP until you meet the standard, then the flag will be removed.
COA2. You fail to make progress in the ABCP, and you will be separated.
You should be aware of this if you failed to meet the ABCP, because the mandatory counseling should have covered what actions will, and may, take place.
