In 2000 and 2001, Russia withdrew by rail 141 self-propelled artillery pieces and other armoured vehicles and destroyed locally, 108 T-64 tanks and 139 other pieces of military equipment limited by the Treaty on Conventional Armed Forces in Europe (CFE). During 2002 and 2003 Russian military officials destroyed a further 51 armoured vehicles, all of which were types not limited by the CFE Treaty. The OSCE also observed and verified the withdrawal of 48 trains with military equipment and ammunition in 2003. However, no further withdrawal activities have taken place since March 2004 and a further 20,000 tons of ammunition, as well as some remaining military equipment, are still to be removed.
