I am slightly surprised (dunno why) to say that I would rate the Belgians railway-station skills as rather higher than the Swedes. For example, the Belgian escalators drill, with rear observation and defence, and generally moving in an efficient, rehearsed manner around the narrow bits of the stations in Brussels was interesting recently. No CGs or cam-cream, but moving in fours and sixes, rifles, pistols, grenades (presumably flash-bangs?), body-armour, individual comms and lots of mags. It looked like they weren't pretending anyway.
