Simple Sound Merge on Model

[Times]

Hello, I'd be very thankful if someone could either:
- Personally do
- Link me a tutorial about
- Tell someone to do
placing a sound on the normal attack animation of this model:

I think it's okay to do it without permission since the author has been gone for over a decade.

The sound to place is this one.
http://soundbible.com/2095-Mossberg-500-Pump-Shotgun.html
It is uncompressed and uncut.

Note: I would use regular WC3 triggering for placing the sound, but they don't overlap, no matter what setting, trigger, etc. I put. The only way for them to overlap is placing it directly on the unit's model or missile, which is also linked here.

Thanks in advance!
