Blackhawk was started by a retired US Navy SEAL. 5.11 Tactical is popular with many PSCs/para-military types.
Some Youtube.com "preppers" & survivalists advise against any gear or clothing that's too "military" or gung-ho saying you should maintain a low profile.
That's not bad advice if you are in a urban area & you don't want any undue attention from looters or street gangs but I wouldn't be leery of using military gear if it works best for your needs.
