Cougar Helicopter
The Cougar is a four-blade, twin-engine, medium-sized, utility helicopter that has seen extensive military and civilian use over the years. In its civilian role, it is primarily used for transportation and offshore support, as well as public service missions, such as search and rescue. Some variants even come equipped with an emergency flotation device, which mitigates the risks of ditching at sea.

For military use, the Cougar comes with variable pylon mounts for external weaponry. Some variants are fitted with a 20 mm chin-gun, vastly increasing its striking power and versatility as a gunship.

Take advantage of extensive customization options featuring different pylon loadouts and over 30 skins, which allow you to outfit the helicopter for every imaginable mission.

MOOSE Pickup
The MOOSE pickup is a light-duty vehicle with a wide range of configurations, serving military and civilian sectors worldwide. It is often used as a means of short-range transportation, or simply as a dependable weapons platform for special forces and non-state actors.

With 40 available texture variants, as well as a plethora of visual customization options and multiple different weapons modules, you can tailor your MOOSE to stand out amidst the chaos of battle.

120 mm Twin Mortar and Commando Mortar
The 120 mm Twin Mortar is a container-sized emplacement that can launch HE, smoke, or laser-guided rounds accurately at incredible distances across the battlefield. The Commando Mortar is a lightweight one-man mortar that can be easily assembled in the field.

RC-40 Micro-UAV
Keep an eye and an ear to the skies - although if you hear one of these drones, it is probably too late! This incredibly compact UAV can be equipped with explosive or smoke charges, which can be detonated remotely or via impact with a target. A scout variant can laser designate targets while maintaining a low profile.
