Javelin Anti-Cheat
Guys, I do not think it is working at all.
Just came out of a game of breakthrough where the top 5 players on the attacking team steamrolled us, 2 rounds straight with very suspicious in-game behaviour. Wall banging, target snapping, enemies TTK very, very short and not registered as headshots, where as defending team despite shooting at them could not kill them, or it took at least 3 players to down them, which didn't happen very often.
Then there is what appeared to be instant reload, as in no cooldown, and weapons breaching geometry when using standard issue ammo. By geometry I mean, a bunch of deployed cover in front of metal crates etc. Another tell-tale way to identify these players I have found is that they always leave before the end of the round and then rejoin. The ones that you do manage to lookup on Battlefield Tracker, well their stats do not match their in-game actions or apparent skill.
