My thoughts: -
The probability of success for a downed pilot defending against ten troops is pretty minimal. Maybe he could take out one or two but his colleagues would not spare any ammo in obliterating the pilot. I have often saved a base by bailing out and defending it against troops that way, but frankly it is becoming a bit too gamey. It was great fun, but it's too much now. The troops should/must be able to shoot back and take down the pilot somehow.
