Greetings fellow Mountain Warrior!
Resident training covers courses that are in ATRRS, to include troop schools. I am not aware of any courses you can do here in Afghanistan but the best person to ask would be your Schools NCO. Given our geographical location, there won’t be many options, if any.
If you have a SOCAD agreement already in the GoArmyEd system, you are not required to go to an Education Center to enroll in classes. I don’t know if you can make it to FOB Fenty but there is an education center there which is located in the vicinity of the “Big Top Gym” behind the PX. The GoArmyEd website has all the information you need to enroll in civilian classes. You will need a Tuition Assistance form signed and uploaded to the site to be able to start enrolling in classes; your company commander is the approval authority.
