Harry Rowe, known as Macer Gifford, is a British former currency trader and volunteer fighter and medic who, between mid-2015 and 2017, travelled to Syria to fight with the Kurdish YPG militia against the Islamic State group, and as of 2022, is a volunteer medic and recruiter for the Ukrainian Foreign Legion in Ukraine. He took his identity from National Hunt jockey Macer Gifford, the brother of four-time champion jockey Josh Gifford. He spent five months fighting with the YPG in 2015 before returning to the UK in 2015. In 2016 he completed a second tour with the YPG in Syria. In Ukraine, Gifford is reportedly "running a battlefield first aid training programme that he first pioneered with the Kurds [in Syria]."
