Dunno, never tried it
IIRC, Halycon gave you permission in WCI to put a few shots across at Maniac if he didn't follow orders, i seem to recall him saying
"Use guns, not missiles, don't waste them"
BTW : I played through WCI again at the weekend, and found out that Maniac skragged the Drayman he was escorting with a HS, the full story was given to the player by Spirit,
Maniac was trailing a Dralthi as it strafed the Transport, he got lock and fired a HS at its engine exhaust, as he launched the missile, the Drathi did a tight half-loop and shook off the HS lock, the HS then aquired the Draymans engine exhaust and severly crippled the Draymans engines, the Kilrathi quickly finished the crippled Drayman off.
