We have found the Syrian military aircraft!
If you already have a few fighters in the air, vector them to engage the enemy aircraft, otherwise launch them!
You can engage the Fishbeds with short-range missiles, like the Python 3 or a Sidewinder, but you should use a Sparrow or an AMRAAM against the Flogger.
The AA-7 are SARH missiles, if you shoot a Python 5 (Range: 0.2 - 15nm) at the Flogger, when he tries to evade your missile the AA-7 missiles will lose guidance and self-destruct.
You can try to engage the Flogger with short-range missiles, but it's dangerous! If you want to do that, switch off the radars on your fighters so that the enemy will have problems tracking them. Then, you can use terrain masking or the clouds to sneak up on the Flogger and destroy it at short range.
A safer option is to engage it with AMRAAMS or Sparrows.
