Does anyone know what these are?:
Relentless
Psychotic
Blinding (flashbangs I'm guessing? but what about them?)
Intervention
Blind Fury

There should be a description to these awards ingame. Take a look at your dog tags.
There should be the information, normally.

They're not dog tags, they are skill kills :/

Relentless is 4 consecutive kills in a row.
Psychotic is 5 consecutive kills in a row.
Blinding is when you kill someone after having concussed them with a Flashbang.
Intervention is when you kill someone before they fire on a team member while using their sights (easiest when killing an enemy Sniper).
Blind Fury is when you kill someone when YOU are blinded by a Flashbang.

You can get demolition based skill kills on yourself I have noticed. For example, you can blind yourself and an enemy with your own Flashbang and then kill the enemy while blind. This would award you both Blind Fury AND Blinding.
