Very rare combat aircraft emerged in Syria (Photo) .

An image was published on social media shows two main aircrafts operating in the Syrian air-forces, including very rare one.

The two planes shown in the image taken at the T4 air base are the Su-24M2 bomber and the M-25RB , the daily Rossiiskaya Gazeta said.

The Syrian Sukhoi bombers underwent a modern upgrade that included sophisticated electronic equipment that allows aircraft known as “bomb trucks” to use unguided munitions and precision guided munitions.

The use of Su-24M2 aircraft against the militias has resulted in heavy casualties.

The MIG-25 RB is a rare aircraft in Syria. Six such planes were found in Syria three years ago, military experts said.
