Lob a molatoff cocktail from above and hit the engine intakes and you can get a Mobility kill.

Armour in built up areas is very risky with out infantry support and the APC's would not be just driving around with out having dismounts supporting them.

This, or spray paint in windows and periscopes. Or, smokey fires in air inlets, crews carry gas masks but not hours of supplemental O2.

Modern armor isn't invulnerable, but as I suggested it isn't easy to take out and likely would achieve similar to 40:9000 or worse in confrontations with civilians. Thankfully armor rolling over civilians like that isn't common enough for me to pull actual statistics, so we have to guess at efficacy compared to knights fighting peasants.

And a knight would frequently be either backed by other knights or have men at arms as well - effectively dismounts.
