M113A3 on Major Gs website.

I was poking around on the Majors website, and noticed the M113A3 page. Is this the same M113A3 as Canada is now intorducing? It is also known as the MTLV or something like that, and has an extra road wheel and chassis plug, with thicker armor, and a new turret.
if it isn’t, then what upgrades have been made to the M113A2?

The US A3 differs from the A2 by several external items, but an extra road wheel is not one of them. Also there is no turret on the US A3, same old .50 cal cupola that was used on the M113A1 and A2.
