The weapons used by the SNA forces are all Russian-made and had been seized in earlier fighting against the Syrian government troops, the statement added.
A video, released in early November by the rebel faction Jaish al-Islam, an SNA affiliate, shows a German Leopard 2 tank. The tank had originally been delivered to Turkey, according to dpa information.
At the time, a spokesman for Jaish al-Islam confirmed to dpa that Turkey had provided the rebel militia with military equipment.
"We were given three heavily armoured vehicles and troop carriers," the spokesman added.
He also said rebels had been trained in using Leopard 2 tanks.
However, an SNA spokesman at the time said those tanks only belonged to the Turkish forces.
Last month, Turkish troops and their allied Syrian rebels launched an offensive against Kurdish insurgents in north-eastern Syria.
