Multiservice tactical brevity code

Multiservice tactical brevity codes are codes used by various military forces. The codes' procedure words, a type of voice procedure, are designed to convey complex information with a few words.

This is a list of American standardized brevity code words. The scope is limited to those brevity codes used in multiservice operations and does not include words unique to single service operations. While these codes are not authoritative in nature, all services agree to their meanings. Using the codes eases coordination and improves understanding during multiservice operations. The codes are intended for use by air, ground, sea, and space operations personnel at the tactical level. Code words that are followed by an asterisk (*) may differ in meaning from NATO usage. There is a key provided below to describe what personnel use which codes, as codes may have multiple meanings depending on the service. These are denoted in-line for each brevity code.

As missiles guide by creating a direct intercept course, this is also used to reduce the missile's speed and thus its ability to maneuver if radar lock is maintained.
