British Volunteer (holding AK-47) and three Bosnian-Croatian members of the unit at the base. The base was located at the old school house in Sijekovac on the Bosnian side of the river Sava. This area named the "Northern corridor" or " Posavina Corridor" saw some of the heaviest fighting in the Bosnian war. The corridor was utterly vital for the Serbian aim of a "Greater Serbia" and the Serbs threw everything they had at the Corridor.
