An ambush? Kinda like this ...Just played a Tiny CMFI scenario against the AI called "Smokey's Challenge".
Two platoons of Canadian infantry with a handful of PIATS move to set up an ambush on one side of a bridge to try and prevent infantry and armor from crossing and holding a couple of VL's.
It was lots of fun. (Perhaps a little one sided)
One tank was immobilized and with no PIAT near I "Assaulted" the tank with a squad and, by god, it actually worked and they knocked it out.
