Go into you sma file called soldier..

scroll down until u see this:

switch_model(id)
{
if ( !shModActive() || !is_user_alive(id) || !HasSoldier[id] )
return
new clip, ammo, wpnid = get_user_weapon(id, clip, ammo)
if ( wpnid == CSW_AUG )
{
set_pev(id, pev_viewmodel2, "models/shmod/Soldier_aug_fixed.mdl")
}

change :
"models/shmod/Soldier_aug_fixed.mdl")
to:

"models/shmod/Soldier_aug.mdl")

and then compile it and copy from compiled, and paste in plugins

i had the same failed and now the model work perfectly
