Does anyone have any information on what it's like being a 92Y in the Active Guard Reserve?

I don't have any direct experience with this, but I have noted a very high attrition rate in my state's 92Y AGR community.

Always attempting to keep the unit’s property book squared away on your monthly drill.

I was a 92Y in the Iowa National Guard, then spent about a year as "active guard". For the most part imagine it as being active army with the bonus of being at home. You'll work 9-5 monday-friday just like a normal job (all national holidays are observed). You get all the benefits of an active soldier. However you'll also be required to be present for "drill weekends" once a month and the required two weeks a year. And it's also important to note this is the army, shit happens sometimes you'll be forced to stay late/come in early and stuff like that. Now, the second part of the equation is the MOS. A 92Y is of course your average unit supply specialist who works in the supply room doing a multitude of things from ordering equipment and uniforms to performing inventories all the time. But in a lot of armories a 92Y will double as the armorer. Many responsibilities come with this and just like your supply sergeant you'll eventually need a security clearance and again since this is the army along with being the unit armorer you'll still be required to perform your supply clerk duties, but I'll say it was an extremely rewarding experience that I had a lot of fun doing. I don't miss the vault alarm suddenly going off at 3 a.m. do to a fault but hey it is what it is.
