M17/M18 MHS: What Is ANOR?

Dear Half-Mast,

TM 9-1005-470-10 (Mar 19) says when firing M17 and M18 pistols that single-hearing protection should be worn, at a minimum, and the allowable number of rounds (ANOR) per day should be limited based on weapon and firing position.

Can you explain ANOR?

Dear B.F.,

Sure! Here’s what you need to know about the ANOR. It’s tied to safety and hearing protection.

Firing more than 3,245 rounds with the M17 from the standing or kneeling position or more than 1,341 rounds from the prone position can damage the operator's hearing.

The same goes for the M18, except that the ANOR for the prone position drops dramatically to only 247 rounds.
TACOM plans to update TM 9-1005-470-10 within the next few months. It will include the correct round count I just mentioned.
  • M17: Standing and kneeling ANOR 3,245; Prone ANOR 1,341
  • M18: Standing and kneeling ANOR 3,245; Prone ANOR 247
Remember, always wear hearing protection when on the firing range, and leaders must be sure that Soldiers under their care don’t exceed the ANOR.
