How long after an APFT can my command do a height and weight, and then flag you?

AR600-9 Chap 3 Para 1
"At minimum, personnel will be weighed when they take the APFT or at least every 6 months."

"4 If the circumstances preclude weighing Soldiers during the APFT, they will be weighed within 30 days of the APFT."

Keep in mind, you are expected to meet height and weight standards at all times. Just like drug testing, APFT, and reporting for duty.

Before my PT test, i would always get taped test. I am 5ft 6in and 195lbs hitting the weights. The thing is if your neck is thick when they average your neck and waist you should be good, as compared to a pencil neck and a fat belly.

Your command can flag you any blasted time you fail to me the standards of the service. So you pass the AFPT at the bare mims, and later in the month, someone says you are looking flabbier. They tape you and you fail to meet standards- BAM hello flag! It's legal and it's the reg.

AR 600-9 Paragraph 3-2 d & e
"d. Commanders have the authority to direct a body fat assessment on any Soldier that they determine does not present a Soldierly appearance, regardless of whether or not the Soldier exceeds the screening table weight for his or her measured height.
e. Soldiers identified as exceeding the body fat standard will be flagged in accordance with AR 600–8–2 and enrolled in the ABCP. They must meet the body fat standard in this regulation in order to be released from the program.

Basically a soldier can be height and weight measured at any time at the discretion of command. If they exceed height to weight ration and fail the circumference tape evaluation, they are then put on ABCP and flagged.

Let me caveat this by saying I am not sure about a reg..but....

Height & Weight are done "in conjunction with" a APFT but that does not mean that they are ONLY done with an APFT.

You are expected to be within Height & Weight standards AT ALL TIMES.

As an example, if I saw a troop who was looking a little "iffy" I would take him to the gym and toss him on the scale. I'd rather find out "before" the PFT than "at" the PFT. (which is never more than 6 months away).

If you are over, you are over. The only real excuse for that is "medical" (something happened that resulted in gaining weight). You are responsible for maintaining weight. Don't get me wrong, a normal deviation of 1-2% (-/+ 3lbs) is "normal" but if you are sitting at "maximum" you should be extremely careful not to be caught over.

So its not me but one of my fellow Soldier. I was looking into it and could not find much on it.

In my opinion, yes! I wouldn't worry about it unless you are going to a school or about to get promoted. Try to keep the upper body workout so you have a bigger neck. If you lose weight because you are getting in shape and you get a bigger neck, it's win-win!
