From Lego City Set 60071
There is I think, paradoxically, a sense of fragility and vulnerability in all armoured vehicles. Granted, when aboard them, you're protected from a greater or lesser amount of offensive weapons depending on the age of your vehicle and its type of armour, and you may have weapons aboard yourself. And yet, the fact that you are in such a vehicle in the first place, and that you are protected, and armed, is just a proof that you are a target from the start, for whatever reason, and all who try to destroy a target will find in the end a weak point to do so.
You should certainly feel more vulnerable than protected if you were to go to war nowadays in an open style half-track vehicle such as mine. Even with a machine gun on the roof!
Fortunately, mine is just a civilian version which just happens to have a machine gun on the roof, more for looks than for anything else, and because all good half track must have one!
This vehicle is, I guess, a MOD, for modified vehicle, as I worked on the base of the Lego half track from City Set 60071 and modified it. I made it longer, added two ladders to climb to the cab, made the bed bigger and added benches all around, added a gate at the rear which, when open, becomes a ladder to help you climb in. I fixed a winch in the front and beefed up the bumper. Oh, and did I mention the machine gun on the roof?
I do not own set 60071 and ordered from Lego the parts for this one (got the wrong wheels, asked for the right ones, got the right ones, and there we are).
