During a mid-fight, at least one Scout should stay alive losing both of its most mobile players can spell disaster for a team. Scout's most effective tactic is to utilize his high speed to ambush enemy players to kill them before they are able to react. He is also often the best candidates for off-classing, depending on the situation. A competent Scout must successfully capture points, control the flank, and be able to finish off enemies weakened by power classes ( Soldier and Demoman).
The Scout is a highly mobile 'clean up' class, used to capture points and move in and out of fights to deal and avoid as much damage as possible.
