Requiring the player to identifty his target, and not shoot at first sight, makes it more challenging. And realistic. I do agree that having, say, woodland vs dpm is too hard. Although they are easy to identify from, what, 5m and less, it can't be expected to be identified easily from 15 meters the wood.
But having woodland vs flora, they are different enough that if you're careful, you'll be able to identify them. It's way different from basketball which relies heavily (although not exclusively) on speed of action to succeed.
When it comes to large scale MilSim events, tan vs green works well, it is simple enough for most people to understand and affordable enough to enforce.
