GE, the 6 year plan, as was explained to me when I first got to my unit, is only a recruiting tool. Sure you get an extra stripe and advance a little faster but you don't get the as many e-enlistment bonuses for your rate (if there are any). If there aren't any re-enlistment bonuses then you don't have to worry about it. In the Coast Guard they give you bonuses for the fist 10 years, after that they figure you'll probably be in for 20 anyway so why bother giving you another bonus. Bonus at 6 years, by the time your second re-enlistment comes around you're already at 10 years.
