Mail Call Episode 22 _dig_

Since self-propelled artillery is so much more maneuverable than towed artillery, why isn't all artillery self-propelled? Self-propelled artillery has been around since World War One, at least in a crude rudimentary form. It really came into its own in World War Two when artillery crews had to keep up with fast tanks and infantry carriers. The reason all artillery isn't self-propelled is that it's too expensive to build every gun around a motorized chassis. A towed piece of artillery is also lighter, therefore easier to transport. The Mail Call team traces the history of SP artillery all the way to the amazing systems of today
