Wait, you mean we can order the Saracen or Silhoulette to fire missiles? I thought they will just move towards the UFO until one gets killed. For intercepts I have 2 saracens equipped with 2 SHIVA cannons, armour, ECM and targetting computer, after firing an AA missile from my base (Yeah, I let the UFO come in close, that way, my Firebird doesn't have to travel far) and it works most of the time. However, occasionally, one of them gets shot down and I have to buy another one complete with accessories.
