1 Combat Engineer Regiment (1 CER, ) is a Regular Force regiment of the Royal Canadian Engineers (RCE) commanded by a lieutenant-colonel. Its headquarters is in the Patton Building at CFB Edmonton (Steele Barracks), Alberta, and it is assigned to 1 Canadian Mechanized Brigade Group.
1 CER was continually involved with rotations to Afghanistan as part of the ongoing war on terror. Due to the regiment's special armoured engineer capability, every Canadian rotation since 2006 had a minimum of an armoured troop from 1 CER attached.
1 CER had six soldiers killed in Afghanistan.
1 CER is different from other CERs as it holds the Canadian Army's armoured engineer capability. Formerly this was provided by the Badger Armoured Engineer Vehicle (AEV) Since 2018 the Badger AEV has been replaced by a Leopard 2âÂÂbased AEV that is known in Canadian service as the AEV2 (still commonly called the Badger, or Badger 2).
