I am currently in the Coast Guard and considering transfering to the Army by means of the WOFT. For aviators how do deployments work? What is generally the length of deployments and how often do you deploy. thanks for the help.

12 months. Deployments are based on unit and rotation. If you PCS after a deployment, you may find yourself in a unit that is ramping up to go....and you just got back.

My brother in law is on his 3rd trip to Iraq in 5 years if that is any help. He's a tanker, though.
