" An elite group composed of military professionals, aircraft and ground vehicle designers and civilians dedicated towards creating an aircraft-delivered (forced entry) ground force that has tracked, mechanized x-country armored fire & maneuver capabilities to execute decisive 3D maneuver alone or in concert with enhanced 2D maneuver forces."
The link really only stated the only problems with Stryker were of weight (air transport) and cost. They tossed in some statistic death Stryker/M113 ratio which is misleading since Strykers are frontline patrol while the Gavin are are taking shotgun.
Another criticism was really against up-armoring the Humvee; that money should not be devoted to Strykers, but Gavins instead. Again this is the fact that Strykers fair better than up-armored Humvess.
