“A field team in Eastern Europe linked to the European Command helped dismantle Soviet Su-25 aircraft and Mi-17 helicopters so that they could be sent to Ukraine.”
The equipment has already been sent to Ukraine. The number of transferred aircraft is not disclosed.
It is noted that a “large centre” has been set up in Europe to supply military aid to Ukraine. There are 110 servicemen from 30 countries who manage the logistics.
