As the attack commenced, some of the insurgents were able to penetrate inside the base and attempted to detonate themselves, but were stopped by coalition forces. Afghan forces also detained five insurgents and destroyed a recoil-less rifle at the scene. After the failed assault, NATO forces conducted an airstrike on a car occupied by 4 Haqqani Network fighters in the area. There was a complex attack against the FOB in early June 2012. Insurgents utilized a local truck packed with 1,500–2,000 pounds of explosives; a suicide bomber detonated his truck bomb on the southern edge of the base, breaching the perimeter and causing significant damage to the base's buildings. The dining hall annex was leveled and the main DFAC (Dining Facility) sustained severe roof damage in the blast. Moments later, ten insurgents entered the breach armed with rifles, machine guns, grenades, and rockets; each bomber wore ACU digital military camouflage uniforms while one wore an ANA military uniform and most wore explosive suicide vests. The attackers were first engaged by two Navy SEALs driving by the DFAC in a Toyota truck, and then by a five-man team consisting of three helicopter mechanics and two vehicle mechanics; who blocked the attackers advance from two directions. After a 7-minute firefight, US service members repelled the attack, killing all ten insurgents. With the last insurgent dressed in an ANA uniform being killed in a ditch. The first insurgent to fire shot a RPG rocket into the front of a Toyota truck hitting the front right bumper but did not explode. Then a Navy SEAL riding in the truck rolled down his window and shot the insurgent. Next two insurgents came around the second wall and were shot by two helicopter mechanics. Two base contractors were killed in the attack when the DFAC annex collapsed, and a US Soldier died of a fragmentation wound to his face from a hand grenade a few days later. Although initially downplayed in the media, in July 2012 both Long War Journal and al Jazeera published an unedited attack video released by the Taliban. Taliban spokesman Zabiullah Mujahid claimed that an airplane on an airstrip at the base was destroyed and that 'tens' of foreign forces were killed and wounded in the attack. The Taliban later released the video of the attack, showing the attackers practicing in Southeast Afghanistan, taking their photos, the group leader showing his shooting skills by shooting 2 machine guns and the suicide bomber in the truck. FOB Salerno was located approximately 25 km from the Pakistan border and the most viable path connecting it to Afghanistan was the Khost-Gardez Pass, which is highly vulnerable to attack and often lead to supply shortages at the base.
