The vehicle

“The Stalwart is a cross-country amphibious load carrier and is capable of carrying a five ton payload over extreme terrain conditions and across inland waters. The vehicle possesses a performance comparable with most tracked vehicles but has in addition the advantages of the ease of maintenance, speed, quietness of movement, minimum crew fatigue and the virtual absence of damage to roads and communication lines.” [1]
