There are a number of locations that have the Brigade dentist slot (TOE). some of these include, Ft Riley, Hood, Campbell, Stewart, Bragg, Lewis, Carson and Drum I think. There might be one or 2 more, Conus ones. I believe that all in Alaska are also TOE, but don't quote me on that. There's alot of smaller posts Sill, Leavenworth, Leanardwood, Polk, Irwin, etc where there are no TOE slots, so you would automatically go into the Profis pool. Everybody is Profis unless you are in a TOE slot. That just means you could get pulled and deployed, nothing to worry or freak out about. But really 6 months, that's a cakewalk compared to the BS of the TOE slot. Also don't believe any of the crap they tell you in OBC about Profis docs getting stuck in some other occupation, (road guard etc)
Maj Pratt-Chambers recently sent out a list of all the posts and if there are TOE slots or not, I deleted it so I'm just going from memory here. You can always talk to her.
