(this is a fanmade weapon and is not canon until helmets says so)
A ISF scientist created the Divison Locater gun to locate lost soldiers such as N.N.. The weapon has the design of a Black SCAR-L with a radar on the top.
The ISF soldiers are outdated and are being replaced with helmets ISF soldiers.
