The M113 FOV are fully tracked, self- propelled carriers, and are either thick skinned (armored) or thin skinned (unarmored). The ar- mored variants are derived from the M113A2 or M113A3, and the unarmored are derived from the M548. The M667 guided missile carrier is a special exception. It is thin skinned, but is not based on the M548. b. All of the variants are powered by a diesel engine and are supported by a torsion-bar suspen- sion. Various product improvements on some vari- ants have resulted in transmission, suspension, armor, and power upgrades. The carriers vary in height and weight, but unless otherwise noted, are considered the same for transportability pur- poses. c. The following paragraphs contain the specific administrative and technical data that affect transportability for each of the individual carriers. Each subsection contains a vehicle picture and the relating transportability characteristics and data necessary for safe movement. For transportability purposes, the pictures of the newest versions (Al, A2, and A3) are representative of the older ver- sions. 1-7-1. M106, M106A1, and M106A2 (figs 1-1 and 1-2).
