Small Scale Military Headquarters

I'm looking for what you think is the absolute best reference sites or material for planes, WWII to present day. I want to be able to check my planes for the accuracy of detail, color, markings, squadron information, pilot history and anything else you can think of. I know a lot of you have a ton of websites bookmarked, please share them with me. When I have all the links or sites or book names compiled, I'll post it here, Thanks.

I posted this earlier, but this site is excellent for aircraft markings from WWII. Indispensible!
