Engineer soldiers train in the bridge-making prior to their deployment in Europe. They are wearing the wool uniform with M41 field jacket. Of special interest are the toe-capped service shoes being worn under the leggings. These shoes, which featured a smooth outside surface and toe-cap, would have been replaced in the ETO by the more common rough-out service shoes. The rough-out service shoes would have featured the rough side of the leather on the outside of the shoe and no toe-cap.
