“From the start the naval Construction Battalions were unusual outfits, mostly because of the men in them and because theirs was a new kind of warfare… Every Seabee found himself doubling in various trades. It was thus the construction men developed their most important tools – improvisation, ingenuity and guts. Often parts, materials and equipment had to be manufactured on the spot in shops hastily thrown together from salvaged enemy materials and tools… But as the Seabee organization grew (from an original force of 3,300 to a peak of 247,155, of which 83 percent were overseas) and its activities increased, the battalions picked up plenty of know-how, enabling them to smooth out and speed up operations.”
