Basic Kill Medals
There are five common kill medals that also earn you a single incredible feat point. These medals include the First Strike medal earned when you score the first kill in a game, the Revenge medal earned when you kill an enemy who recently killed you, the Avenger medal earned when you kill an enemy who just killed a teammate, the Reload This medal earned when you kill a reloading enemy and the Kills from the Grave medal earned when you kill an enemy just after you yourself have died.
Vehicle Hijacking
There are two hijacking-related feats that qualify as a Halo: Reach incredible feat. If you hijack a land-based vehicle then you receive the Hi-Jacks medal and an incredible feat point. If you hijack an aerial vehicle then you receive the Sky-Jacks medal in addition to an incredible feat point.
Special Kill Medals
Halo: Reach includes 12 special kill medals that earn you one incredible feat point when you execute them. You receive the Close Call medal when you score a kill and have no shields left; conversely, you receive the EMP kill medal when you kill an opponent with collapsed shields. You can also receive the Showstopper medal for killing an enemy that is about to assassinate a teammate or the Yoink medal for killing an enemy that is about to be assassinated by one of your teammates.
