"Game Saver" medal ?

Imgur

Anybody knows what the requirements are for this one ?
Just got it in a Team Slayer game… I was definitely carrying my team, being the only one with a positive K/D, but it’s not the first time it has happened so I’m not sure it’s related to this specific medal.

Someone was about to get the final kill on your teammate to win the game and you stopped them from getting it. Thus you were awarded the protector and game saver medal.

Ooh, I see.
That’s interesting. Thank you !
