The year is 1995. Faced with either leaping into the unknown with a clean-sheet system or plugging along with legacy platforms, several contributors to Armor Magazine decided to pursue a middle ground. In the November-December edition, they unveiled their contraption: An Abrams-chassis 52-caliber (same as the PzH2000 and Archer) self propelled howitzer with an autoloader and a whopping 80 rounds inside.

AFAS/M1 would fire 4 to 8 rounds in a Simultaneous Impact Mission (SIM) between 6-40 km. All rounds will impact within 4 seconds (first-to-last round). This requirement can be attained with an effective combination of a battle management system, fire control system, global positioning system (GPS) and an autoloader.-claim for its power from the article.
A resupply vehicle on the same chassis would also be designed. The AFAS/M1 had a target weight of 55 tons.
For all the unusual elements about its design, in practice this beast would have been deployed conventionally. In action, it would have served with heavy divisions/brigades in the usual format. It could be simmed by using the offensive stats of the PzH-2000. Yet it still stands out, in appearance if nothing else.
