Some suggestions for neat armour and weapon textures based on their names, kind of like nation-specific armour and weapons.

Knight - I suggest basing it off the Gothic Armour or the Knight's Armour from the Epic Knights Mod.
Juggernaught - Only for Diamond and Netherite. It could look like either super-heavy medieval armour or perhaps more like German WW1 Stormtrooper armour.
Gas Mask - Purely aesthetic, just a WW1 gas mask, would be fun for larping.
Crusader - Armour based off the infamous Crusader knights.

Longbow - A bow... but it looks longer.
Zweihander - A large two-handed sword.
Buckler - a small circular shield.
Knight's Shield - Basically it's the same shape as the current Cultist shield, just looks more traditional.
Halberd - This is for the axe, just makes it look neat.

These are all purely aesthetic and only meant to add more variety to the appearance of weapons and armour in CCNet.
