Larochelle was deployed to Afghanistan in 2006, serving with 9 Platoon, Charles Company, 1st Battalion, Royal Canadian Regiment. He took part in combat operations around Kandahar, including
Operation Medusa.
Battle of Pashmul On October 14, 2006, Jess Larochelle was manning an observation post on Charles Company's flank. The company was positioned around Pashmul, guarding a road between two Canadian bases. Larochelle was the machine gunner for the observation post. Around 3 p.m., the company was attacked by a force of over 50 Taliban, who were equipped with rocket-propelled grenades and small arms weapons. The forward observation post took a direct hit and Larochelle was wounded, briefly losing consciousness. When he awoke, he discovered that two men of his company, Sergeant Darcy Tedford and Private Blake Williamson, were dead and three more had been wounded. Larochelle was seriously injured in the initial attack, with broken vertebrae in his neck and back, a detached retina in one of his eyes and a blown eardrum. Though he was partially deaf and had limited eyesight, Larochelle mounted a swift and aggressive defence of the OP, firing his machine gun he quickly ran out of ammunition. He then began firing
M72 rocket launchers at the enemy, firing fifteen 66-mm rockets at a force of about 20–40 Taliban insurgents heavily armed with rifles, light machine guns and rocket-propelled grenades. Larochelle's actions helped protect his wounded comrades and hindered the Taliban attack. He provided covering fire on the company's flank, which was otherwise undefended, and his counterattack bought the company enough time to mount a secure defence of the post. The Taliban were forced to withdraw, and were unable to significantly attack their main target which was the rifle company base. ==Recovery==
