In Team Fortress 2, being disguised as a scout or medic results in a speed boost.

The statement that being disguised as a Scout or Medic in Team Fortress 2 results in a speed boost is false. In Team Fortress 2, the Spy class has the ability to disguise themselves as members of the opposing team, tricking their enemies into thinking they are one of their own. While disguising as a Scout or Medic might help the Spy blend in visually, it does not grant any speed boost abilities. Each class in Team Fortress 2 has its own unique set of abilities and attributes, and disguising as a different class does not grant the disguised Spy any additional advantages beyond the visual deception of the enemies.
