The Sniper's SMG in Team Fortress 2, was originally intended to be the Scout's primary weapon.

The statement is true. The Sniper's SMG in Team Fortress 2 was originally intended to be the Scout's primary weapon. This decision was made in the early stages of the game's development, as the designers wanted to give the Scout a versatile weapon that would allow him to engage enemies at longer ranges. However, during playtesting, it became clear that the Sniper's playstyle and abilities were better suited to using the SMG. As a result, the decision was made to switch the weapon to the Sniper class, where it remains today as one of his primary weapons.
