This is a short Demoman voice line, lasting about 1.7 seconds, in which the Team Fortress 2 demolitions expert says he is ready when you are, delivered in his gruff Scottish voice. It feels confident and fired up, like a call to start the action together. The line comes from Team Fortress 2, where Demoman uses it to signal he is prepared for the fight ahead.
