Building a properly scaled motor vehicle can be a challenge, considering the unnatural proportions of the LEGO minifigure. That challenge was undeniably met by Robson M who has not only built a pair of well-proportioned vehicles scaled to fit their LEGO occupants but also meet the additional challenge of making the convoy military armored vehicles. I was thoroughly impressed by the Humvee (on the left), and the Oshkosh M-ATV (on the right) based on the build alone, but when I looked up the reference material, I was even more impressed by so many amazing details captured in plastic.
For the Humvee, I think my favorite detail, besides the front grill, is the round tile for the air intake on the front right fender. The Oshkosh features a roof-mounted armored turret with a gun, and there is plenty of room in the back for any extra gear needed. I bet there is even room for a case or two of MRE rations.
