Some 10,000 Israel Defense Forces reservists will suspend their volunteer reserve duty in protest of the government’s plans to overhaul the judicial system, a large protest group announced Saturday evening.

At a press conference in Herzliya, leaders of Brothers in Arms announced the move, the latest to send shockwaves through the Israel Defense Forces, which is struggling to stem a growing flood of reserve troops dropping out of volunteer duty to protest the overhaul, as defense officials warn the phenomenon could affect national preparedness.
