BL35358K - STRYKER BLUE FORCE 1 AND 2 TRACKERS - AFV CLUB
Blue force tracking is a United States military term for a GPS-enabled capability that provides military commanders and forces with location information about friendly (and despite its name, also hostile) military forces. In NATO military symbology, blue typically denotes friendly forces. The capability provides a common picture of the location of friendly forces and therefore is referred to as the blue force tracker. When all capitalized, the term refers to a specific defense contractors' system, but the capability is found in many military and civilians mobile apps.
