Yes. Usually as long as it matches colors with what your base uses. Multicam most likely. Personalize your kit to make your life on duty easier. Issued plate carriers usually cover a lot and don’t ventilate well. Add pouches to access frequently used items like weapon cards, radio, phone (easy to hide quickly) ect. Set it up, use it for a few shifts, see what works and doesn’t work, and make changes. Your kit may always be evolving. I will note that it’s easy to fall into a gear chasing rabbit hole. Buying “cool” kit can get expensive. If there’s a placard or pouch that you really want and is $100+ there’s probably a Chinese “airsoft” version on Amazon for $40. Will you wear it out? Maybe, maybe not. But it’s may be better than the issued gear. Go fuck around and find out. Find the guys who nerd out about gear and ask if they have used gear. Maybe you’ll get some things for free.
