Occupational Therapy in the ARMY?

[John]

I'm studying to be an OT and recently was told about the ARMY being a good option for this route. Is there anybody that can fill me in on exactly how this program operates? Chance of deployment/ how close to combat/ etc. To better clarify my questions...
1) How long is the contract?
2) Are you guaranteed deployment?
3) If yes, are they able to put you into combat for any reason?

Thanks and hope someone can help.
