[AtE] Wasteland vehicle improvised weaponry

[Luke Bunyip]

Went and rewatched Mad Max II aka The Road Warrior and one thing struck me; the lack of pintel or turret mounted automatic firearms.

If the setting doesn't have a glut of automatic weaponry and ammunition conveniently lying about, what other options does an aspiring warrior of the wasteland have for arming his minion's vehicles? Arbalests (possibly with a Polybolos type repeating action), pneumatically* powered harpoon guns and multi barrel dart guns? Could a black powder shaped charge be used as a warhead, rendering the above as a TL2-3 equivalent to the RPG?

What other options could there be?

Should I be delving into my back issues of the Pyramid?
