Transmitter



A transmitter is a small electronic tracking device used to monitor somebody's movements.

The Boss and the Soviet Union
The supposed KGB spy EVA, under the alias of Tatyana, supplied Aleksandr Leonovitch Granin with shoes that had a transmitter in them, in order to monitor his movements and draw attention away from herself. The transmitter shoes were allegedly a recent KGB development at the time of the mission. Nearing the conclusion of the Virtuous Mission, The Boss planted a transmitter on Naked Snake when getting into the CQC battle against Snake so that her Cobra Unit could trace him, which was eventually discovered by Colonel Volgin while he was torturing Snake. Snake was later fitted with a transmitter in his back by Major Ocelot after his interrogation by Volgin.

Big Boss and the Militaires Sans Frontieres/Outer Heaven
During the Peace Walker Incident, after Vladimir Alexandrovich Zadornov was arrested by Big Boss's mercenary group, the Militaires Sans Frontieres, a transmitter was planted on him in case he tried to escape. The MSF used this to track him down when he successfully escaped their custody several times, though they were unable to do so during his final attempt.

A transmitter was hidden within Solid Snake's items while he was imprisoned in Outer Heaven during the Outer Heaven Uprising, which he later recovered and was forced to remove.

United States Government/NATO
Gustava Heffner of the StB implanted Kio Marv with a transmitter shortly before his capture by Zanzibar Land agents during the Zanzibar Land Disturbance. However, Zanzibar Land deduced this and it was removed from him and given to Black Ninja, before FOXHOUND commenced Operation Intrude F014.

Kenneth Baker and Donald Anderson were implanted with transmitters prior to their capture by the rogue FOXHOUND unit, during their revolt on Shadow Moses Island. Decoy Octopus took the transmitter into himself via a blood transfusion from Anderson, after the latter died under torture.
