A Buck Main is an action in Rainbow Six Siege which can be accomplished by all level and ranks, from level 1s to level 200s, from Coppers to even Diamonds. They all will become a Buck Main. It is when a player either grenades them-self or their teammate by accident and the people who performs this action is the character Buck. This only occurs with Buck and only Buck.
