Being deployed has nothing to do with your rating as an ME or being a reservist. The Coast Guard uses their reservist and in some case alot! The Port Security Units which is almost all reservists having been deployed numerous times since 9-11. Their typical deployment is a 2-3 month work up with a 6 month deployment. If you go a MSST or PSU your going to get deployed. It's just a matter of time. If you go to a SECTOR your less likely to be sent overseas but your still fair game for a 60 day stint in the Gulf. Bottom line if you join up expect to deployed in some form or fashion during your career. It could be domestically but it will happen.
