The analyzer's blueprints were presumably either procured by the Militaires Sans Frontieres during one of their missions or awarded/supplied to them by one of their employers at some point prior to being hired by Ramon Galvez Mena and the Costa Rican government to drive out the mercenary force currently invading the country.
Shortly after their leader, Big Boss, managed to report his findings to MSF from investigating the supply port at Puerto del Alba, the MSF's R&D team managed to start developing the analyzer. After the analyzer's completion, it was able to list the enemy soldier's best suited skill area and his overall fitness for battle. Further modifications however improved on its search range, search speed, and the accuracy of its assessments. Various improvements to its accuracy included allowing to analyze for any items/equipment he had on his person, such as bullets or rations, as well as specific skills the soldier had.Eventually, the analyzer was upgraded to not only allow for the complete scanning of an enemy soldier in a short period of time, but also provide intel on the amount of escorts of various tanks, APCs, and helicopters, along with the captain's overall skill, as well as glean in on possible weaknesses on the AI weapons, even without the soldier carrying the analyzer into battle.
Behind the scenesEdit
The Analyzer is an item in Metal Gear Solid: Peace Walker, which can be developed immediately after accessing Mother Base for the first time. Although it first appeared in Peace Walker, similar gameplay elements previously appeared in Metal Gear Solid 4: Guns of the Patriots as the Solid Eye, and in Portable Ops Plus as the Headhunter career and, to some extent, the FPV in that game allowing players to see the strength of an individual enemy soldier by the amount of stars they possess. If the player attempts to use the Analyzer on a Monster Hunter via the pause menu, it will not display any data, instead listing the entry as unknown. Scanning any ghosts during the third Paparazzi missions or the Dead Man's Treasure missions yield the same results.
