Does anyone know of any tour opportunities for a reserve 68W?

If you live close to your unit, you can go in any time other than BTA. And...if it isn't close, check to see if there is another unit close by that you could use govt computers. Or, talk with your nearest recruiting office to see if you can log onto one of their computers.

Not sure where you're looking to go but RP has a tool where you can search for existing positions and units.

Check out Tour of Duty (mobcop)You will have to access it from a government computer however, as they restricted access to a lot of .mil URLs from personal computers.

Sure; a DA 4187 requesting:
MOB for 12 month assignment to the MFO.
Assignment to American Samoa/Guam MEPS
Johnstone Island use to be available but that mission completed sometime in the late 1990's

Where is your unit. I assume you’re guard or reserves. The 7236 MSU (reserves) is at fort Bragg at the McArthur Reserve Training Center. Last I remember when I was there is a CPT PA (C) assigned there very friendly and a great mentor link up with them do an RST there one month and connect

Most interesting ...Thanks for the share...
How far are you from the Unit
