Ever since Halo 2, medals have been a significant feature in Halo multiplayer. These virtual accolades signify cool accomplishments performed by the player, such as killing two opponents within a few seconds of one another. Each game has a unique list of medals, and Halo Infinite is no different.
In the Technical Preview, medals were shown slightly to the left of the player's reticle whenever they were earned, and they could also be seen in the Post-Game Carnage Report. Each medal has a unique design and one of four colors indicating rarity:
The rarity of the medal affects a few in-game behaviors. Uncommon medals pop-up when they are earned, but are not announced by Jeff Steitzer. Rare and above medals are announced by Jeff Steitzer, with more enthusiastic announcements for Epic and Legendary medals. In addition to being announced by Jeff Steitzer, Legendary medals have unique messages that appear in the killfeed whenever a players earns them. For example, earning the Ninja medal causes the message "[Player 1] NINJA'd [Player 2] - hate to see it." to appear in yellow font.
This video shows how the Ninja killfeed message appears after earning the medal. Unfortunately, it is difficult to read the message in this video unless the resolution is set to 1080p. The text can be seen in the killfeed to the left.
Most of these medals were screenshotted from my own matches, but a few are using images sourced from Halopedia. If I missed a medal that can be shown with video or image proof, please let me know!
Note that the below medals are listed in alphabetical order. This unfortunately causes some oddities with the ordering of spree and multikill medals in the Legendary section.

Summary
The medal system for Halo Infinite has some similarities to previous installments. Medals are awarded for multikills, sprees, and other cool actions, just as they have been since Halo 2, and the cooler medals are announced by Jeff Steitzer when they are earned. However, as with every Halo game before it, the actual medals have been changed, both in terms of what can be earned and the visual appearance of the medals. Here's what we know about the Halo Infinite medal system as we saw it in the July 2021 Technical Preview.
Halo Infinite's medals use a colored rarity system. I am unofficially referring to these rarities as Uncommon, Rare, Epic, and Legendary.
Uncommon medals (green) are not announced by Jeff Steitzer, and they are the easiest medals to earn.
Rare medals (blue) are the most common medals announced by Jeff Steitzer.
While easy to earn, they generally require that the player perform a special action.
The Double Kill and Killing Spree medals also use this rarity.
Epic medals (purple) are announced more enthusiastically, and they are harder to earn than Rare medals.
Performing a particularly stylistic action (such as turning 360 degrees around just before killing someone) will award a player one of these medals.
The Triple Kill and Killing Frenzy medals also use this rarity.
Legendary medals (red) are the most difficult medals to earn.
Earning one of these medals will result in a unique message appearing in the killfeed for everyone to see. The message shown is different for each Legendary medal.
These medals are awarded for kills earned in highly unusual and hard to perform ways, such as killing someone with the impact from an M9 Frag Grenade.
The Overkill, Running Riot, and all medals above these use this rarity.
Several medals have been renamed from their historical appearances.
Beat Down (as it appeared in Halo: Reach through Halo 5: Guardians) has been renamed to Back Smack.
Rocket Mary has been renamed to Fire & Forget.
Snapshot has been renamed to No Scope.
Untouchable has been renamed to Nightmare.
Invincible has been renamed to Boogeyman.
Inconceivable has been renamed to Grim Reaper.
Unfriggenbelievable has been renamed to Demon.
Snipeltaneous has been renamed to Quigley (a reference to Quigley Down Under).
