Is "IT" in the military the same as citizen professional/corporate? As in, mostly "administrator" level work or is it more expansive? I'm just curious in the sense that it either may be all encompassing like programming too, or perhaps things I never heard of. Just curious, thanks! I appreciate the reply. I'm guessing you can do the ASVAB before "signing on?"
