Pros
Can be a fun either a fun Job or an Immediate realization, that you made a very bad decision. If you do not mind working with salty old ex-career military co-workers who think they are still serving and act accordingly, your golden. If youve never been around these people, it can take some adjustment.
Cons
No electronics depending upon where you work, if you work on the JT4 J-Tech II contract (which is a terrible contract). Arcata and JT4 work together, on this contract. Nepotism (wife and husband, mother and daughter) in many roles working in the same departments, to a degree so blantant, I have never seen or even heard of. Email Blasts/Reply All to companywide Email for announcments as trival as a BBQ party in a location hundreds of miles away - with nothing to do with you.
If you travel - plan to pay for all expenses up front, out of your own pocket. You are then required to spell out exactly how you paid for your own travel amd any fees that Hotel chains typically charge. So yeah - be ready to pay your own way, if you travel for the company.
