It would be nice if someone could identify the unit. It’s not something I’m well-versed in, and unfortunately the markings on the Carrier are just about impossible to make out at that. But Fort Garry Horse seems likely, since the photos were taken in the area of where this map (from that thread) has a green arrow going past Oostkerke:
FWIW, where it says “Oostkerke” it would be rather more correct to put “Wolphaartsdijk”.
