After being reminded by 
Editor in Chief Bill 
that we hadn't issued our 6mm SF armoured warfare rules (Iron Cow 2103AD) in PDF, I've been busy typing and formatting away. As with previous PDF releases, it will be A4 with lots of colour photos of toys in action (which will be mainly from the dedicated Brigade Models line of Iron Cow miniatures, but also include some GZG, Scotia, etc.) and available from Wargame Vault.
Further good news is that I have been inspired by the forthcoming Russian releases from Brigade that I have been working on a dedicated supplement (Za Rodina!) which introduces the Neo-Soviets into Iron Cow and comes complete with background, unit TO&Es, vehicle and troop stats, some scenarios and a mini-campaign. This will be only available in PDF at the same time (or just after) the main rulebook finds its way onto Wargame Vault.
This may be the start of a number of supplements, as I already had a project on the South African Confederation underway which could be expanded, and have a lot of material on the New Guinea War that we did not finalize into a planned supplement.
