The Swiss MOWAG Piranha III and the Canadian General Dynamics Land Systems LAV III are in my opinion essentially the same vehicle. General Dynamics bought MOWAG last October.
Cool.
After looking around a bit it seems that the LAVIII is indeed a weapon system built on a Stryker platform. But in the end...it isnt a Stryker and does not have the same weapon systems, targeting or C&C capabilities.
