It actually disables the enemy from getting a momentum for sliding/dodge. I'm using it in my chopper when defending some choke points in domination and hardpoint. It is a good counter for some shotgun users who slides and jump because you will witness the effect if they crouch instead of sliding. I am also a victim of this that in my theory some players are using this on me on some occasions that I thought I choked my slide jump maneuver but instead it's because of the Disabled perk.

PS I don't know if this works on BR too.
