The purpose of the report is to determine characteristics and limitations in subject vehicles and indicate steps for improvement. Most crucial need is for improved driver's vision. It is now necessary for him to make three distinct changes as to means of vision during the most crucial moments in landing the craft as follows: At the outset, he drives with the hatch open, seat up and head out. He then lowers seat and opens forward hatch, closes overhead hatch, tilting periscope out of the way so that he can get the maximum of the remaining unobstructed vision. He closes forward hatch and adjusts the periscope so that he retains that small field of view during the remainder and most crucial steps of the operation. It is exactly during this time that the craft is in the greatest danger of broaching or being turned end over end as a result of momentary loss of power or steering. It is believed that a large proportion of the losses, which in battle have amounted to as much as 50% of the landing craft, occur as a result of the distraction caused by the effort to retain adequate vision and from lack of vision.
