Campaign missions often feature armored vehicles like tanks, APCs, or attack helicopters. These require specific tactics to destroy. For ground vehicles, rocket launchers (RPG-7, Javelin) are your primary tool. If you don't have one, look for weapon caches or pick one up from fallen enemies. Alternatively, C4 can be planted on vehicles and detonated. For tanks, aim for the rear armor or tracks, which are often weaker points. For helicopters, sustained fire from LMGs or assault rifles can eventually bring them down, but rockets are far more efficient. Always use cover to avoid their heavy weaponry and prioritize taking out any infantry support they might have before focusing on the vehicle itself. Some missions provide mounted turrets or air support options to deal with vehicles.
