Imported Sound when attacking?

[qbrtux]

I need a little help,
How do i get an Imported sound to be played when a unit is attacking?

For example: I imported a marine with a Sniper Rifle, looks cool and all, but when it is attacking you hear nothing but silence.

A trigger with the action "A unit attacks" wont do, you can simply order him to stop and still hear the sound.
