Much thanks to Julia Gorin:
Though the video is grainy and I could not discern uniform detail, the vehicles were another matter. These are Brits. The transports they are using to help the mujahedin are Warrior AFVs (Armored Fighting Vehicles), the counterpart of the Bradley in use by the U.S. military. The Brits were stationed in central Bosnia. If I recall correctly, even that drug-addled adventurer, Anthony Loyd (”My War Gone By, I Miss It So”) told of Brits shielding the jihadists from Croats.
The video you are watching shows footage of Arab Muslim Mujahideen (Odred El Mudzahidin) being brought into Bosnia on UN transports to carry out part of the Islamic war against the non-believers, in this case the Serbs.
Formed under the orders of the Bosnian Presdient Alija Izetbegović, the Mudzahidin, also know as the ‘7th Muslim brigade’ were a unit made up entirely of Muslim Arabs shipped over from the Islamic world to engage in the wider Jihad and to help establish Muslim states within Europe.
