Thermite is one of the original hard breachers in Tom Clancy's Rainbow Six Siege, the tactical shooter Ubisoft released in 2015, and his exothermic charge is built for breaking through reinforced walls that other operators cannot open. That breaching role made him a familiar pick in matches and a recognisable shorthand for forcing an entrance. Short game clips later spread through meme edits, streams and soundboards, where the Thermite association alone signals a bold push. It remains useful because the reference is instantly clear to Siege players and easy to drop into a joke.
