Army officers (or anyone else in the know), will deploying past your YMAV cause you to get moved to a new AIM cycle?

HRC won't know that you're deploying when you're being slated at your cycle.

Either your YMAV should be adjusted to after your deployment date, you'll return from deployment early to PCS, or your command can process a mission essential deferment.

If you're going to be deployed your unit should place a stop move code on you with an end date of 90 days after the expected return from deployment. Your branch manager (I forget the term for officer branch managers) should be able to adjust your YMAV based off that and you'll fall under the appropriate slating cycle (AIM) for your YMAV.

If you are slated in your AIM and afterwards coded for deployment your unit must either return you in order to PCS or request a mission essential deferment. You will not be reslated under another AIM unless you are completely removed from your assignment
