Special Forces in contemporary warfare will be expected to conduct operations 'By, with and through': enabling local partners to fight against common foes. Back in 2015, elements of the UAE Presidential Guard deployed to Aden in Yemen in an attempt to forestall and turn back a seemingly inevitable Houthi annexation. It could have been the decisive moment in a campaign that had seen the Houthi rebels take over control of almost the entire country. On 13 April 2015, 8 operators were helicast off shore and hours later were deep in a battle that was to last well into June. It was not a one-sided action by any means: there were several serious tactical failures and defeats of local forces by the Houthis, any of which could have spelled the end of the mission. Yet UAE leadership doggedly doubled down each time and the results speak for themselves. Peter talks to Dr Michael Knights about the battle, the decision-making, and the logistics of this important battle. A case study in the realities of SF 'By, With and Through' missions.
