Can anyone explain what actually counts for this beyond matching the damage type on an NPC no less than 5 levels lower, as in:

is there a certain % of damage you have to deal on an special damage NPC to get "credit" for it in team mode,

does it still count for you if it was another player that got the fatal shot?

What about if it was a skill or grenade that actually got the fatal blow?

What if I don't start landing shots until after their shield is gone?

Any other conditions to be aware of?

I ask because it seems there's times when the kills aren't stacking when they should.

I searched briefly but couldn't find an answer. Is there some sort of schedule or triggering conditions for elite patrols in the open world? I've only seen one and don't know if I'm just missing them or if they're super rare or both.
