[Unsolved] Units have no attack sound or projectile

iv been using some unarmed marine models in my map, i cant figure out how to fix this. They have an impact sound (heavy metal bash and what not),
but no attack sound or projectile.

effect sound turned off? xD

nope even if i add a sound or projectile nothing happens. i use an item to equip a wepon model in the marines hand would there be a way to add an attack sound and projectile through that item?

or could i add an attack sounf and projectile through triggering

That's in the model. You need to edit the model. For more info about this, ask somebody who is decent in modelling (at least with Sound Nodes).

Yes,Avator is right.You must edit the model,but firstly,you should ask for permission to edit it,don't forget that thing,and especially if you want to upload it somewhere.

Is your problem detached now???
Else I could try it with another method...
