Military call sign

Common card · No. 285198

Military call signs are call signs (or callsigns) or a specialized form of nicknames assigned as unique identifiers to military communications. In wartime, monitoring an adversary's communications can be a valuable form of intelligence. Consistent call signs can aid in this monitoring, so in wartime, military units often employ tactical call signs and sometimes change them at regular intervals. In peacetime, some military stations will use fixed call signs in the international series.
