The other advantage of Stryker of M-113 is armor. The Stryker is built to withstand heavy machine gun fire. It's supposed to have a ceramic overlay for RPG/shaped charge warheads - which ran into development problems - slat armor is the expedient replacement. M-113's have repeatedly proven to be too vulnerable without significant uparmoring. The IDF has completely redone theirs, but I doubt they fully trust even that level of protection any more given what happened in the recent fighting in Lebannon.

Really, I think the whole Stryker vs. M-113 debate is kind of besides the point. The current mucky mucks in charge of procuring/developing new systems are perfectly capable of turning in an M-113 based platform which has all the problems of a Stryker and spending just as much money while they're at it. I think better oversight by Congress, the Department of Defense and the Army could have brought either project in for a lot less money than was/is being spent.
