Per my statement in my previous post, the US DOD/Army will not buy a foreign designed vehicle, aircraft, and/or equipment off-the-shelf. They may decide to buy the design with the intention of re-designing it to their liking and/or specification. When was the last time the US bought an off-the-shelf weapon system? The answer is "Never".Because it'll cost a trillion dollars, then get cancelled. I'm exaggerating just a bit but if you google NLOS-C, Palladin, Commanche, ARH-70 etc you might come to the conclusion that the DOD has a serious issue with specifying and delivering working weapons, and that buying MOTS might work. I don't pretend to know how different Stryker is from Piranha however.
