Callouts are a staple of competitive online games since the time of Quake 3D. They provide a shorthand to the players for quick and easy communication. While some game developers have incorporated callouts in their game, sadly in Overwatch these are a courtesy not extended by Blizzard. YET!
Overwatch is a fast-paced team-based shooter game. Victory relies on working together and taking appropriate countermeasures against enemy actions.
The biggest benefit of having callouts is to relay strategic actions to your team. Callouts are used in Overwatch to give instructions to teammates to go to specific locations, inform them of enemy location, instruct to capture sniping positions etc.
