The Company of Heroes 3: Hammer & Shield Expansion Pack adds two new Battlegroups for multiplayer and skirmish modes: the USF Advanced Infantry Battlegroup, focused on elite Ranger units, artillery observation, and heavy artillery strikes, and the Wehrmacht Italian Coastal Defense Battlegroup, which emphasizes defensive structures, coastal reserves, and powerful artillery. It also introduces a new British Air and Sea Campaign Company for the Italian Dynamic Campaign, enabling airborne assaults, rapid deployment of anti-tank guns and howitzers, and support from aerial and naval bombardments. The expansion includes four premium cosmetic packs for various in-game vehicles and infantry.
