I remember good old days where you go to a NATO vs Eastern Block event and play as Eastern Block you just look for NATO camouflage to shoot at... There was no "light, dark, tan, green, blue, yellow, black etc" teams. If someone decided to wear Russian made clone of US woodland and got shot by own team, well sucks to be him

I guess things changed over the years.
To the OP, I still keep my SSO Gorka-E/Smersh setup for about 10 years and still like it.
There are also events happening now where there is absolutely no camo restrictions. Just like in real life, when it's not a large scale military operation. Anyone is allowed to wear whatever they choose. At times people don't even know who/how many are going against them.
