why not ?
For "killing" a tank, you do not need to destroy a tank !!!
You just need to kill/neutralize the crew...
the vastly superior weaponery of USA got stuck against black pyjama guys (viets...), and exemples like this are numerous.
Let us think your tank got ambushed and the commander (the top of the tank being never buttoned up except in battle ... and even not always, cf. book: "Tigers in the Mud ") got killed by a well-thrown spear... then the warriors quickly jumped on the tank, dropped in, and slaughtered the crew...
But I would love to have tanks (and any other mechanical units) being captured!!! Ex., in a battle, you have a little chance for the tank not be destroyed, but captured !! or the ship...
It gives another meaning to piracy, especially in the Gulf of Aden...
