their = there
Since I am in the guard maybe I can shed some light on this...
There are positions in your state which support the guard. some of these are called full time technicians. Say you are a mechanic on your weekend drills..the state has full time technicians that work at certain armories that support your unit. Supply clerks is another one. You must be in the guard to get these positions.Once your in the guard and past basic and your mos school, you come back and look at the big board at your armory of posted jobs (or go online) then find one you are qualified for and apply.
(most of these jobs require you stay in the guard as a condition of employment, for as long as you have that job)
Then look on the board later on..some other position might have opened up with a higher pay grade and a chance for promotion..re-apply as needed. There are also full time active guard positions that work the same way..
You show up for work in uniform...have every other Friday off (NJ) and get paid the 1st and 15th of every month
..and I have seen some shops unionized.
Good luck!
