Battlefield 4:Weapons and Gadgets

Like past Battlefield games, Battlefield 4 will feature four Kits in the online Multiplayer. Each kit will play its own role in team based combat. 

• Assault: The Assault Kit is the Medic of the team. They heal and revive fellow teammates with the Med Kit and Defibrillators. Now they can heal one soldier over time with a First Aid Kit, and they have new 40 MM Flashbangs.
• Engineer: The Engineer Kit is the Engineer of the team. They repair friendly and destroy enemy vehicles with free-fire, lock-on, and wire-guided missiles and other tools. Engineer can use any PWD (also known as SMG) that is available.
• Support: The Support Kit is the Heavy Gunner of the team. They lay down support fire with LMGs and indirect mortar fire, and supply ammunition to the team. Other explosives they can use include Claymores, C4, and the XM25.
• Recon: The Recon Kit is the Reconnaissance member of the team. They relay intel to the team on enemy infantry and vehicle locations while providing sniper support. Recon can once again serve as the spec ops role with Carbines, C4 and Claymores. 

Campaign gameplay shows off multiple optics on weapons, similar to Medal of Honor Warfighter. Snap to a long range optic or use the iron sights on the side.
