"Whether you're a private security company, paramilitary force, rebel militia, hot housewife, radical insurgent, unhinged lottery winner, over-zealous neighborhood watch group, or just a military hobbyist with a worrying amount of disposable income, we've got you covered."
Warstock Cache & Carry is a business that sells military and utility equipment, vehicles, and more. The player can buy their products off their website.
They sell off-road vehicles, tanks, airplanes, and helicopters. Aside from their standard military equipment, they also sell heavy-duty vehicles such as the Airport Bus, Bus, Mule and the Journey (which defies the purpose of the website).
It is possible that they are distributing the military gear illegally, as it seems that any citizen can buy their products, including the Rhino Tank (as implied by its tagline).
The original skin of the website displayed a Barracks with a full-bed canvas, with a slightly different color scheme, different from the one in the final game.
Before the Ill-Gotten Gains Part 1 update, vehicles' images would be flipped depending on their position with new content/unlocked vehicles, such as the Bus, which could be displayed as a right-hand drive vehicle depending on the number of vehicles currently on the website.
This was patched consequent to the website's new layout after the aforementioned update.
