Nah it isn't easy to climb up, all vets are lined up there, and we have to admit they are pretty good at talking and making other people work, so they usually end up raising to mid level ranks in fed.

Regarding form collect info and fill it up bro. I don't know what happens if you don't fill, but I know that will for missing info during clearance interview again. I don't know what will happens you didn't provide at all, they might give result as undertrrmined .
