Unit attack style

I am making a unit that has a flamethrower. I changed the missile art from rifleman to breath of fire, but it still shows him attacking like usual, with the fire over it. How do I kill the initial missile art, and what is a good flamethrowe missile art?

There are serveral you could use, some I can think of now:
Missile:
RedDragonMissile(Black Dragon Whelp)
LordOfFlameMissile(FireLord)
LavaSpawnMissile(Lava Spawn)
PhoenixMissile(Phoenix)
Ability:
FireballMissile(Firebolt)
BreathOfFireMissile(Breath of Fire)
Alfb Target(Item Attack Fire Bonus<Target>)
Spawned Effects:
Flame ThrowerSpawObj(Flame ThrowerSpawnObj) <Probably the best!

Yea, I use an Orb ability that casts a dummy spell with the spawned effect Flamethrower as caster art on 100% of attacks. Works/looks absolutely great.

You're trying to make a Firebat out of a Marine, I take it? *yawn*
