Well, keep in mind I was quoting another poster, who did not mention any time requirement. So I can't answer that part of the question. However, your argument assumes that the volunteer wasn't going to volunteer, wasn't going to spend those hours at the station anyway.
Given the fact that I'm already spending over 25 hours a month at the station anyway, the no-brainer for me is to take the education for $6 instead of $6,000. So they tell me I have to be at the station 25 hours a month...big deal...I'll tell them that of the ~32 I spend there already, they can have the first 25. And maybe they'll count the extra ~7 or so hours off the end, lol.
Well, if you're going to be there anyway, and have no plans to do anything but for the term requirement, then it's a free 6 grand, I suppose. My comments were intended for those who vollie just because they think they're getting a deal by having the vollies pay for their medic class.
