The Hemmings Auto Blogs have a post on a wonderful Wierd World War II vehicle: the Minenraumer, which apparently is kept in a Russian museum.
Road To Hell WWII Skirmish Rules
Road to Hell is a set of free wargames rules for WWII skirmishes. The author writes:
1.0 SCALE
This is a skirmish game so one miniature represents one man and one model vehicle is one vehicle. One centimetre corresponds to around 2 metres and a turn represents 10-20 seconds of real time.
2.0 YOU WILL NEED…
You’ll need a couple of units or squads (one per player) of around 8-15 miniatures each to play Road to Hell (for more details see the Army lists), a few six-sided dice (hereafter referred to as d6) a ruler or tape-measure (all measurements are in cm) and a minimum recommended playing area that measure 80x80cm (30×30 inches) for 28mm figures and 60x60cm (2×2 feet) for 20mm figures. Considering that these are small skirmishes, scenery is very important. Avoid battles in open ground as they will be very lethal and not particularly satisfying
Occult WWII Card Game
Occult World War II is a two player Warpspawn Card game. You need to make your own cards to play.
Unternehmung 25 Postcard Wargame
Here’s a great concept: an entire hex and counter style board game on a post card:
The second V-Mail Postcard Game, UNTERNEHMUNG 25, chronicles the Axis invasion of Yugoslavia in 1941. The basic game system is similar to the of its predecessor, Malaya. New elements include German mountain troops, Panzer Corps, air support, and the bombing of Belgrade, as well as the effects of mountain and river terrain. Hungarian and Italian troops also make an appearance.
Can you, as the Germans, make a lightning-fast assault and capture Belgrade in time to release units for the upcoming invasion of Russia? As the Yugoslavs, can you derail the German timetable and buy time for the Allies to react? It’s all up to you.
