It would go on to be known as the Battle of Wanat, the most costly single engagement for U.S. forces in Afghanistan to that point. Nine U.S. soldiers would make the ultimate sacrifice alongside another 31 U.S. and Afghan troops who were injured. But their defense allowed 46 paratroopers, three Marines, and their Afghan allies to hold against a coordinated attack by over 200 insurgents.

The attack on the U.S. forces near Wanat in Afghanistan centered on Kahler, a combat outpost in the area. COP Kahler was a strong position, but it faced a number of defensive weaknesses. First, it wasn’t the high ground in the valley. That’s a compromise military leaders sometimes have to make, but you really don’t want to have to defend a position where an enemy can fire on it from above.
Another problem was that civilian buildings came close to the outpost. This included a mosque that the attackers would misuse as a fortress to get an advantageous position against the defenders.
Finally, and probably most importantly, COP Kahler was not yet done. Engineers had been working for weeks to prepare for construction, but the actual building only began on July 9, four days before the attack would come. And a number of important defensive measures wouldn’t be complete for weeks or potentially months.
Some of the defensive positions on July 13 were still just concertina wire and guns, though some positions were protected by boulders, HESCOs, or hasty earthworks. The task force had planned for the possibility that an attack would come early, while the outpost was still vulnerable. But the intelligence estimates did not anticipate an attack by hundreds, and the assets at the base didn’t either.
But Chosen Company of the 503rd Parachute Infantry Regiment was holding and building Kahler, and they had prepared well for an attack with what they had.
The defenders’ TOW missile launcher was mounted on a HMMWV that could be driven around the site, but a platform was quickly built to give it better fields of view and fire. And there were two mortars, a 120mm and a 60mm, to provide additional muscle.
And the Americans had built observation posts in the territory around the outpost. These would allow American forces to inflict casualties from higher ground, but it would also deny the enemy a chance to occupy those three positions, meaning that was three fewer positions the insurgents could attack from.
And the engineers were busy from July 9 to 13, filling as many HESCOs and digging out as many fighting positions as they could. They were able to provide significant protection to the 120mm and many fighting positions before the attacks came. The 60mm mortar had a pit and a few sandbags, providing some protection. (Some of the defenses and fighting can be seen in this video.)
There were signs in the buildup to the attack that it was coming. Men in the nearby bazaar were seen watching the Americans and seemingly doing pace counts to figure out distances. The number of children in the village slowly dropped, and Afghan contractors refused to bid on some services for the base.
So when Capt. Matthew Myer saw five shepherds traveling together near the base he immediately prepared for a complex attack, using his TOW and mortars to hit the men shifting around the base. Five shepherds will rarely travel together because that many shepherds signals that there are either too many shepherds or too many goats in one area for normal grazing.
But before Myer could give the order to attack, two bursts of machine gun fire signaled the enemy forces, and then a rain of rockets came onto the U.S. warriors. The Battle of Wanat was on, and the enemy had seized the initiative.

That first volley came in the first hours of July 13, and it contained a very large amount of RPGs. While the Army history of the battle gives no official number to the rockets that hit the base, quotes from the men who fought in the battle described an absolute rain of rockets that left dozens and dozens of tail fins on the ground around the Americans. A radiotelephone operator later said that the “RPG fire was like machine gun fire.”
The insurgent forces had sneaked up close to the outpost and unleashed hell, and the volume of fire indicated that there had either been a major buildup of rockets at these positions or else runners were keeping the shooters well supplied. This rain of explosions took the TOW launcher out of the fight and suppressed a mortar and some machine guns and grenade launchers.
Myers and his men were suddenly struggling to achieve fire superiority. The mortar crew got at least four high-explosive rounds off despite the incoming fire, but were driven back from the weapon by the RPGs and machine gun fire. Rounds were flying in from buildings and trees near the outpost, and the fire was concentrated on the mortarmen.
But they weren’t the only ones in trouble. Another main objective of the enemy force was cutting one of the observation posts, OP Topside, off from the main force. While the OPs provided protection to the COP, they would also be vulnerable to enemy attack until the engineers were done clearing vegetation from the fields of fire.
A mortar crewman was injured by an RPG, and then another was hurt while dragging the first casualty to safety at the command post. The TOW launcher and HMMWV exploded, and it injured an Afghan soldier, knocked out some American communications equipment, and dropped two unexploded but unstable missiles back onto the defenders.
The artillery assets supporting the outpost sent death back at the attackers whenever they could, but they were firing 155mm howitzers at high angle. Danger close starts at just over 700 yards, and anything closer than 600 yards in rough terrain is simply too risky to fire. The automatic grenade launchers on the base had a similar problem.

The weapons that were available were fired at such a high rate that many of them began to overheat, and then the only .50-cal went down after an enemy round struck it in the feed tray cover.
But the worst of the fighting for the Americans took place at OP Topside. Only nine Americans were there at the start of the fighting, and the insurgent activity made reinforcing them a dangerous and tricky task, though the paratroopers would do so successfully multiple times.
The OP had its own artillery observer, but he was wounded in that first RPG volley. A paratrooper at Topside was killed in that same volley, and another died just moments later while attempting to throw a grenade. Another was wounded so badly that he could not fight.
The six men able to fight, including the forward observer, were forced to work through their own injuries and beat back the attack. Fortunately, the observer had sent a list of pre-planned targets back to the gun lines days before, and so artillery was able to send some assistance despite the fact that the observer could not conduct the calls for fire.
The defenders attempted to get the upper hand, but their own crew-served weapons went down from overheating or ammo shortages, and then one gunner was killed while firing his M4.
Finally, reinforcements from the main COP moved out. But the three-man team lost one soldier en route to a wound in the arm. Soon after they arrived, the enemy made it through the wire.
The attack was repulsed, but the two reinforcements were killed, and so was another soldier. A short time later, a sergeant moved forward to suppress fighters in a nearby building and was killed. Only one soldier was left in fighting shape with another three seriously wounded.
The defender managed to take out an enemy position with a light anti-tank weapon, giving most of the survivors just enough time to fall back to another position. But in their haste, they missed that the forward observer was severely wounded but still alive.
This artilleryman grabbed a grenade launcher and fired every round he had and threw every hand grenade he could reach. Just before he was forced to make a last stand at the OP, four men from the COP reinforced him, and Topside remained in American hands.
But a new attack, once again led by RPGs, strained this control. Every paratrooper on the OP was wounded, and one would die soon after. A platoon sergeant gathered a new force of seven paratroopers and two Marines and once again reinforced the OP, arriving shortly before the Apache attack helicopters.
Gun runs by the helicopters with their 30mm cannons finally drove the attackers back and allowed this larger force to protect the OP. Another platoon from Chosen Company arrived to help out their brothers-in-arms. This force brought multiple machine guns and two automatic grenade launchers with them on HMMWVs as well as multiple anti-tank rocket launchers.
The quick reaction force assaulted into the bazaar, driving the enemy from nearby buildings while suppressing other positions with the trucks. QRF fighters threw out smoke to mark insurgent positions and the Apaches eliminated them. Slowly, the volley of RPG fire lessened and, four hours after the attack began, the terrorist forces finally began to retreat.
Medical evacuation crews landed under fire to get the wounded out, in at least one case evacuating a casualty while an Apache made a gun run just 30 yards away. This limited American losses to the nine paratroopers already killed. A massive surge in U.S. and Afghan forces occurred July 13 with Afghan commandos coming in to clear the nearby village house-to-house and gain intelligence.
The biggest surprise for the Afghan commandos came when they searched the Afghan National Police station near the compound. A massive cache of weapons was there with most of them having been recently fired. But the evidence was that they had fired in support of the insurgents, not against them. The police chief and others were arrested.
Over the following days, American air assets pummeled insurgent positions, and future Chief of Staff of the Army Mark Milley set up operations in Wanat. An estimated 20-50 enemy fighters were killed in the fighting.
Despite the hard-won tactical success, senior leaders decided that holding Wanat was simply too costly and drained resources from more fruitful fights elsewhere. Chosen Company was pulled out.
