Flank:

Flank means taking a route to attack or pressure the enemy from the side or behind instead of pushing straight through the front line. In Overwatch 2, flanking is used to catch opponents off guard, split their attention, and create openings for a team fight.

Heroes with high mobility or stealth often flank, but any role can do it when the map and enemy position allow. Good flanks depend on timing, map knowledge, and escaping safely after the engagement.
