Forward operating base
Description: In its most basic form, a forward operating base consists of a ring of barbed wire around a position with a fortified entry control point, or ECP. An ECP is a controlled entry and exit point of the FOB and typically has positions to protect personnel against personnel-borne improvised explosive devices (PBIED) and vehicle-borne improvised explosive devices (VBIED), plus blast mitigation with standoff protection.
More advanced FOBs include an assembly of berms, concrete barriers, gates, guard towers, pillboxes and bunkers and other force protection infrastructure. They are often built from Hesco bastions.
