YMK United has been founded in January 2010 by current leader Lokithor. First the team was just a gaming community with an aim of creating a respectful group of casual players. With the success of the team on ESEA, ESL and Faceit tournaments on Counter Strike Global Offensive the community was then called a team with the new objective of establishing teams for Major Leagues. In 2014 the team joined members with another "Clan" and got the "United" state in our name.

Now our Team is both a big gaming community and a Major league participator in Rainbow Six Siege. After our major appearance in Pro Scene the Pro Team name was changed to Macer Tactics and the gaming community name stayed as YMK United.
