And the aluminum armor makes it burn nicely when hit with a hot enough round.
I agree with you about the pork issue. The "not new" issue is also big, as the development costs have already been amortized, so a new production run gives fewer opportunities to pad the bill
I've been looking, but haven't found an indentification of the metal used for the Stryker's armor. It probably shares the "advantage" of making a great illumination flare when really hot!
