In my current dev version of my WWII mod, I've got things like that. In the end, it's determined by the order you equip them in - the last one you put on or take will be the one that affects the skin. For example, in my mod, if you're holding an MG, you get a different soldier model with some grass in your helmet and ammo belts across your neck. But I've also got a paratrooper vest that changes your character model into, well, a paratrooper. If you put on the vest and then take an MG, then your character model will be the MG model. If you've got an MG and put on the vest, then your character model will be a paratooper.

Ah thanks, you've basically done exactly what I had in mind.

Any chance you could link me to your mod please? I wanted a WWII mod to play with!
Thanks a bunch.

I'm holding back on this rather big update until I can get a basic D-Day map up and running. You can find the mod in the Released/WIP mods section, it's called Running with Hedgerows.

What I'm trying to achieve with my mod is that you equip a sniper rifle and get a ghillie suit. would I have to write in every single weapon classed as a sniper rifle or is it possible to use the weapon tags that squads use, like how sniper rifles have a "sniper" tag, and silenced weapons have a "silenced" tag?

The weapon tag is solely used for squad set ups - nothing else. You'd have to do it with every single weapon. But, lucky for you, there's only 5 sniper rifles in the vanilla game - the M24-A2, Dragunov, PSG-90, Barret M107, and the VSS-Vintorez (if you could count that as a true sniper rifle). If you do want to replace the soldier model, here's the bit of code you need to put in the faction file (you might already know this, of course):

Ah ok I understand, thanks. It'd be a copy and paste fest so it probably wouldn't take long to do it that way but i was going to add custom models for medics, machine gunners etc. so there'd be a few more than 6 models to add.

How exactly have you added your tiger tang to your RWH mod? Have you overwritten the original tank.vehicle files and added it that way, or is there a line of code for adding it to a faction/map?

Medics would only require one of those model_requirements lines. But machine guns would be the same deal. But like I said, you could always go the route where you only use the model change when you have a machine gun that's part of your own faction.

The tank replaced the original tank file, but it's out of date now, since each faction has it's own tank.
