The video contains no dialog, instead narrating with text from a computer. It begins with the request from a UNSCBattle Group, Sol Defense Group 3/A-5, requesting repair and resupply. Once the request has been granted, the video then goes on to show production of SRS99D-S2 AM Sniper Rifles, Marine and ODST helmets and suits, M12 Chaingun Warthogs, D77-TC Pelicans, BR55HB SR Battle Rifles, and M6G Magnums on the assembly line and ready for action in a Misriah Armory facility on Mars. It also shows several shots of the enlistment of UNSC Marines into a unit called S4/BAG/2/5 (including the addition of a barcode to the back of a Marine's neck, as well as being injected with an augmentation drug or electronic ID such as an IFF transponder), and then the arming of the marines. Finally, the short cuts to a marine holding a BR55HB SR Battle Rifle stands on war-stricken ground when an explosive detonates next to him, before ending with "Halo 3, Finish the Fight."
