Taken from the D-X044 Bullfrog marketing material:

Outfitted with Raktos-12 armor, the “Bullfrog” offers groundbreaking protection against mines, IEDs, grenades, mortar fire, and anti-tank artillery. The advanced Vaelite-ballistic windshield is both shatterproof and bulletproof—capable of withstanding .50 caliber armor-piercing rounds. The RhinaMax tires can withstand bullets, small explosives, and have been designed to resist deflation effects when punctured, allowing the vehicle to keep moving at reduced speed for a limited distance.
