Files for Fall of France & Road to Dunkirk are now in the Vassal library. Game packages are available for download.
Of course there are extra units for experimentation and creativity. Of particular note are the Royal Marines and Grossdeutchland Regiment/Division.
The Royal Marines OOB has been expanded to support a battalion sized landing. If you use it with the USN extension, you can conduct some landing operations.
Operation Claymore comes to mind, but are lots of other raids too. I hope to get graphic files to create a Royal Navy extension, so the marines can call upon their own guns.
Grossdeutchland has been linked as an optional for the earlier eastern front games. All the scenarios in which the Grossdeutchland Division appears should have counters available in the GD colors, as well as support units for the motor infantry regiment in Fall of France. The 1943-45 version as a panzergrenadier and panzer should be coming after Broken Axis and Burning Tigers get their support.
The support project to-do list is South Flank, June update, Burning Tigers, Broken Axis, Saipan/Mariannas, Lib'44, Army at Dawn. In between those are supplements like Land Cruisers, GD'44 and so forth. Those get sweezed in as practical.
