The first to show up back in the day at NAVWEPSTA had an armored steel shell, at least 1/4" thick, that surrounded the interior personnel compartment. They were heavy and slow, and the jarheads, who handled the security duties at all Naval weapons stations then because nobody did it better, hated them. It got tiresome listening to the bitching at the club. :yes: The auto trannys were especially funky and breakdowns were frequent. These were among the first batch the military fielded, and they had teething problems, most all later corrected I guess.
