It means you need to kil an enemy in a single shot of your weapon and you have to repeat this 10 times to complete the tier.

Example: a headshot using any sniper will kill an enemy instantly in a single shot! You can also use any shotgun if none of your enemies are wearing any close quarters combat set but you must kill an enemy in single shot if you're using a shotgun. To do that get as close to your enemy as possible.

Hope this helped
