While Call of Duty games may not strictly adhere to traditional radio call signs, they serve several purposes, both practically and thematically:
Identification and Communication: Call signs offer a simple way to refer to characters in the game. For example, Bravo 6 signifies that Captain Price is in command of B Company3.
Tactical Roles: Call signs can denote a character's position within a team, such as Bravo 2-6 designating the Commanding Officer of Platoon 2 in B Company3.
Immersion: Call signs enhance the game's realism by mirroring military communication practices1.
Camaraderie: In the Air Force, call signs help solidify bonds between aircrew and improve unit cohesion1.
Confusion: Call signs can confuse the enemy as to who is talking to whom1.
