Shaftoe consults the instructions. It does not matter that these are printed in Russian, because they are made for illiterates anyway. A series of parabolas is plotted out, the mortar supporting one leg and exploding Germans supporting the opposite. Ask a Soviet engineer to design a pair of shoes and he’ll come up with something that looks like the boxes that the shoes came in; ask him to make something that will massacre Germans, and he turns into Thomas Fucking Edison. Shaftoe scans the terrain, picks out his killing zone, then climbs up and paces off the distance, assuming one meter per pace.
