Big Boss, as well as his Militaires Sans Frontières, made use of the device during the Peace Walker Incident in Costa Rica. When upgraded in R&D, red squares indicated any enemies that were near the operative, providing the exact enemy locations in the immediate area.

Behind the scenes

The Surround Indicator is a device that is first introduced in Metal Gear Solid: Portable Ops. It was created specifically to tailor to the PlayStation Portable's gameplay needs.[2] As such, it is always displayed in the top right part of the screen. In the expansion pack Metal Gear Solid: Portable Ops Plus, the Surround Indicator is used in a similar manner, but also utilizes symbols to show the approximate locations of enemies or access points: a triangle facing upward indicating that the soldier/AP is above the player; a square indicating that they are on the same level; and a down-facing triangle indicating that they are below the player. It is also needed to find the exit in the latter game's Infinity Mission mode.

In Metal Gear Solid: Peace Walker, the Surround Indicator is a selectable item that can be utilized by Mother Base's R&D Team and improved upon. The two respective models of the Surround Indicator are based on their appearances/usage in Portable Ops and Portable Ops Plus.
