War of Valor: WW1 Mod

The mod adds custom 3D WWI blocks, including trench walls, sandbags and barbed wire, along with mud and dirt slabs for no man's land, mortar props for trench defense, and brick and stone types for buildings in wartime maps. A proning mechanic lets players lie down in the trenches.

Weapons and uniforms cover early-war British and German designs, with working rifles such as the Gewehr 1898 and the SMLE, sidearms, steel helmets and reload animations for several First World War era firearms. Other rifle models and sidearms are listed as coming later, and Russian Civil War content may follow. The mod is Forge only, built for 1.21.1, and runs on client and server. Players need it installed to join a server running it, and it works in singleplayer worlds too.
