Ma'am,
I would never turn down a chance to deploy especially a short tour, if I was still able and eligible I would deploy in a heartbeat, I always loved going to new places and experiencing new people and cultures, it helps to round you more as a person and SM, at least in my opinion.
I would jump on it if I was in your shoes.
I would deploy. Deployments are becoming few and far
between. It will be the only time you will do your real world mission. What
looks better? Conducted 300 training missions or conducted 300 missions in
Afghanistan while supporting combat troops? That's an easy call. Real world experience
always trumps training. Think about it, you just came out of a year of
training.....I learned more as a deployed PL then I did in garrison.
It's an issue of credibility. To me, combat/deployment is "real world". It's where we take all of our training and garrison experience and actually apply it.
It's where we discover what ACTUALLY works, what doesn't work, third order effects from our actions, how to manage those effects, etc...
Basically, combat/deployment is where we do our REAL jobs.
In my personal opinion, if you have never deployed, all of your training and knowledge is still in the theoretical stage, because you've never applied it in the real world. All you have is what you were told, and what's worked in training/garrison, which as I stated earlier, is NOT the "real world" we train to operate in.
Without practical experience in the real world, all of your training will push you to no higher than novice status (regardless of rank or nifty schools). It's practical application that truly nets you knowledge, and not just theory.
The only setting that matters is combat/deployment. The rest is just training for that environment.
