Police commander Kudai Rahm Shakir only had six men with him when the Taliban started firing at his post in Afghanistan’s Helmand province. The phones weren’t working, so he couldn’t call for help. In the ensuing shoot-out, which lasted through the night, all but one of his colleagues were killed. A bullet went through Shakir’s jaw, shredding his tongue. The unit’s machine gun was destroyed. As the enemy got nearer and nearer, Shakir resorted to lobbing grenades to stave them off. What he couldn’t do was run away – he didn’t have any legs.
