[TANKS] Re: M113 design progress
go back a couple of posts and you will see the cost. I might add, those costs include the cost of the material (they supplied the steel, beat that). they measure cost on the material obviously, unless you supply your own, and the length of time that your job occupies the machine. The formula is unknown to us mere mortals and would no doubt be their trade secret, but that is how they calculate it.
