Ack-am, or antimatter weaponry, was a ground combat weapon which utilised accelerated antimatter rounds. The weapon fired nano-pellets -- at a fraction of the speed of light -- which contained traces of antilithium, but were insulated by ablative normal matter until impact.

Ack-am: Accelerated anti-matter. Weapons system.
- description from the official RS glossary 
- It was said by Ana Khouri one did not wish to be on the same continent as their target when using such a weapon; however, during her brief battle with Sudjic it took more than one shot to defeat the armoured traitor. This is either a testament to the strength of Ultra power armour or to their propensity to exaggerate their technological prowess.
