I’m brand new to military gear and I want to buy my first uniform set for range days and hiking (not trying to impersonate anyone, just want something durable). I’m seeing surplus listings, “tactical” copies, and a lot of different patterns and cuts (BDU, ACU, combat shirt/pants, etc.).
Before I spend money, what should a beginner know about sizing, materials, differences between genuine issue vs replicas, and what’s actually practical for normal outdoor use? Also any common mistakes to avoid when buying online would help. I’m in the US if that matters.
