Tech school as prior service is awesome. (its halfway between baltimore and DC at Fort Meade) the barracks you live in suck (it an army base) but it is a 1 minute walk from a huge Class 6.
It will be about 3 or 4 months.. It is an Army school and you attend with all services.. So thats a unique experience.
As far as CCAF I cant remember how many applied but I think I got at least 12 credits.. there are 4 CDC's
Vol.1 COMSEC/OPSEC/ EMSEC/ COMPUSEC/ basic customer service stuff
Vol. 2 Optics and light theory I think.
Vol. 3 Operational Photography (this is the meat and potatoes of the job)
Vol. 4 Computer and electronics info. also info about printers.
Quite easy. I finished them in about 2 months averaging 90's... It took almost 1 year to take my test though because my supervisor at the time kept making us wait.
A typical week varies from base to base but for the most part we work banker hours: 7:30 to -4:30. always have time to take PT and it is really easy to get time off.
I work in an office with 4 other photographers and I happen to be the highest ranking so I kinda of play the NCOIC role, without all the power. But We have 2 photographers each week go out and spend all week with a specific flight on base and just stay and shoot them. Every aspect of their job. at the end of the week they will come back to the office and put together a picture story. (you will do this in tech school) For example, they shot the phase dock last week.
1 photographer will be in charge of studios for the week. They shoot official portraits and full length photos for special duty assignments. They shoot print and get the pictures to the customers.. think of Walmart 1 hour photo.. except we have have more time to turn the photos around.
Then the other 2 photographers cover the location jobs. this can include group photos, pictures for Public Affairs or the newspaper, just anything that doesnt fall into the previous categories. My office re-wrote or OI and we dont shoot retirements or re-enlistments or anything like that unless there is an O-6 present. it was taking up too much time supporting events that arent mission requirements. especially because everyone and their mom has a 8 MP digital camera these days.. they dont need us..
Other than that just a bunch of odds and ends and random jobs. Depending on where you get stationed the mission will be different so its hard to say.
think that about covers it all.
