Treaty established in Vienna a body composed of all Treaty members, which was called the Joint Consultative Group (JCG), and which dealt with questions relating to compliance with the provisions of the Treaty. The group aimed to: Resolve ambiguities and differences in interpretation Consider measures that enhance the Treaty's viability and effectiveness Resolve technical questions Look into disputes that may arise from the Treaty's implementation Implementation After the treaty entered into force, a 4-month baseline inspection period began. Twenty-five percent of the destruction had to be completed by the end of 1 year, 60% by the end of 2 years, and all destruction required by the treaty completed by the end of 3 years. The principal accomplishment was the large-scale reduction or destruction of conventional military equipment in the Atlantic Ocean to the Ural Mountains (ATTU) region during the first 5 years the Treaty was in effect.

In addition, they have conducted/accepted over 4,000 intrusive on-site inspections of military units/installations, and of specified areas.

Also, NATO members with newer equipment, such as the United States, agreed to transfer some of this equipment to allies with older equipment.

NATO officials disputed this and stated that the US bases were not intended as permanent and thus could not be seen as a breach. However, it was then reported that the agreements signed with both Romania and Bulgaria in 2006 specifically allowed for permanent bases under direct US control and The Washington Times also had obtained the confirmation of a senior United States official that the facilities were intended to be permanent. Former Soviet republics A June 1998 Clinton administration report stated that Russia, Ukraine, Belarus, Armenia and Azerbaijan were not in compliance with the CFE treaty. Violations ranged from holdings of treaty-limited equipment (TLE) in excess of CFE ceilings to denial of full access during treaty inspections. The report concluded that the compliance issues were not "militarily significant" and Russia and Ukraine, the former USSR
