Ive served in an infantry unit in the Israeli army as a 1st leftenant. Lots of combat experience and knowledge. Ive finished the army a while ago and have always been a fan of the British army. I want to show my solidarity by possibly volunteering or joining. I have British citizenship. Whats the procedure? would I even be allowed to join? and if so.. would I have to renounce my loyalty to Israeli reserves that Im currently serving in?
