Police units in the United States tend to use a tactical designator (or tactical callsign) consisting of a letter of the police phonetic alphabet followed by one or two numbers. For example, "Mary One" might identify the head of a city's homicide division. Police and fire department radio systems are assigned official callsigns, however. Examples are KQY672 and KYX556. The official headquarters callsigns are usually announced at least hourly, and more frequently by Morse code.
The United States Army uses tactical designators that change daily. They normally consist of letter-number-letter prefixes identifying a unit, followed by a number-number suffix identifying the role of the person using the callsign.
Informal designations are also used for some services, especially broadcast radio, but strictly speaking these are not callsigns and there is no guarantee that they are unique.
Tacticaldesignators or identifiers (often called tactical callsigns) also fall into this category.

Laser designator and acquisition devices are designed to enhance current capabilities of artillery, naval gunfire, and aircraft in the delivery of munitions on ground targets.
Unless using offset designation procedures, the LDO must designate only one target and not move or search with the designator while it is on and aircraft are in the area.
LGM designator coding is important because it counters the use of simple enemy laser countermeasures and prevents the seeker from homing on other reflected laser energy.
