name one occurence when a primitive club wielding warrior has tricked a tank into getting stuck between two trees. bet you cant.
Not a lot of battles in which tanks have faced primitive club-wielding warriors, but American infantry neutralized a German Panzers advance with exactly this strategy in some parts of the Battle of the Bulge. (Panzers are not good forest/jungle weapons.) Since it doesn't involve the use of the defender's weapon, whether it's a rifle or a club doesn't matter.
And yes, the Battle of Endor is an excellent example, but I would only have brought that up if I was playing a mod.
Some of the anti-tank tactics that the Northern Alliance employed during the early phases of U.S. involvement with the war with the Taliban bear mentioning. They invented successful cavalry OFFENSIVE tactics against modern armor. Pretty impressive.
