I found these while surfing the web.
We're getting a small look at GD's pitch to the US Army. Even if they fail to win the AMPV project. Even if they fail to win the GCV project. Upgrading the US Army and Marine Corps M1 Abrams with diesel engines would be a nice, long term project to keep them busy for a few years.
That alone would be impressive, but they've taken it a step further. If you click here, it'll take you to a website called "A leaner, more agile ABCT (Armored Brigade Combat Team)" and it has a calculator that shows all the savings possible if the Army follows GD's advice. In light of the budget issues we're facing its a real nice pitch.
