This is only for the Commando model. This functions just like a normal skin pack. Installation:

Commando_MHPlayerSkins.utx   --> goes in /Textures
Commando_MHPlayerSkins.int   --> goes in /System
Commando_MHPlayerSkins.utx.uz   --> goes in your redirect

Put the first two files into both your client and the server. Add a single line to the server ini:

ServerPackages=Commando_MHPlayerSkins

and you are good to go. Switch colors in your player setup like normal:

1) Be *SURE* you have RED TEAM selected as the team while you are choosing. MH will force this if you don't. Even though you are using RED TEAM, you will still see other color choices below.
 
2) Select the Commando model and then below you will see choices like 
>MH Merc Blue
>MH Cmdo Yellow
>MH Necris Green

3) Choose any skins that begin in MH and you will be that exact skin on-server and everyone will see it.
