An AC-130H Spectre, Nail 22, flew a reconnaissance mission over the peak prior to the landing and saw no enemy activity, but it was called away to support other troops before Razor 03 and 04 arrived at the landing zone; MAKO 30 team leader was uneasy at the speed with which the sweep was conducted and wondered whether they had the right mountain but he dismissed his doubts and trusted the Spectre's technology. At around 0245 hours, as Razor 03 flared to land at the LZ and was immediately fired upon by machinegun and RPGs, an RPG struck just behind the cockpit, starting a fire in the cabin. As machinegun rounds penetrated the unarmored Chinook, another RPG, seconds after the first, hit the Chinooks right-side radar pod, which blew out all electrical power to the helicopter, particularly its miniguns and navigational systems. The Chinook was hit by a further 2 RPGs and more heavy automatic weapons fire from at least three distinct firing points (particularly from a supposedly abandoned DShK position). The Chinook set down at a slight depression, shielding the pilots from the DShK's fire. The pilot made the call to take the stricken helicopter off; as he brought the Chinook back into the air, PO1 Neil C. Roberts fell out of the open ramp. One SOAR crewman grabbed hold of his pack but lost his grip. Razor 03 attempted to return and retrieve him, but the damage prevented proper control and the helicopter was forced to make an emergency landing in the valley about 11 kilometers (7 mi) away. Roberts fell 3 m (10 ft) into the snow covering Takur Ghar and activated his infrared strobe to mark his position. Razor 04 returned to the peak to attempt to rescue Roberts, as the Chinook offloaded MAKO 30, they came under immediate fire from the DShK, though it was relatively unscathed and left the AO after MAKO 30 successfully disembarked. At first, the insurgents didn't spot MAKO 30 in the early morning darkness, MAKO 30 split up into two-man pairs to conduct bounding movements, making good ground until the enemy spotted them. One team ran across a concealed al-Qaeda bunker and killed 3 fighters before the SEALs were suppressed by other fighters with PKM machine gun. The firefight lasted 20 minutes before the team leader decided to order his team to break contact, USAF combat controller Master Sergeant John A. Chapman (then Technical Sergeant) and two SEALs were wounded. Mako 30 was forced off the peak due to its losses and requested the assistance of the quick-reaction force mainly made up of Rangers from the 1st Battalion Ranger located at Bagram Air Base, led by Captain Nate Self. Master Sergeant Chapman was mistakenly believed to have been killed prior to Mako 30 withdrawing from the peak. Alone and wounded, facing superior numbers of enemy insurgents, drone footage showed Sergeant Chapman killing at least two of the insurgents, one in hand-to-hand combat, before being killed himself.
