Will my work exp be enough?

That is very encouraging. But I just want to maybe better elaborate my concerns.

From my limited time spent browsing the forums its seems that most schools want at least 2 year of full time work exp. post UG. In my situation I will only have about 15 months of full time active duty service as a result of the mobilization. Now this The rest of my time in the Guard (about 2-3 years) is going to be made up of part time service and extended periods of training.

Is this something that will hurt me?

I would like to get a full time civilian job now, however the train up, deployment, and follow on schools that I will be doing after the deployment end up greatly fragmenting my time. Finding employment outside of another part time position under these circumstance will be difficult.

I guess I am hoping that the quality of my experience outweighs any issues of time. Which should be the case given the fact that I have a very important role in the mission that is actually completely different from what I trained for and is supposed to be done by someone that is much more senior than me.

You have great experience from your military service. I would not be concerned about your military experience if I were you. However, gaining additional civilian/corporate experience will never hurt your chances.

You are still young and are below the average age for most MBA programs. Gain some of civilian experience and you will be a great MBA candidate. Best of luck.
