Tanks: Attack at 3, Defend at 3, Move 1, Cost 6
   Only Britain, France, Italy, Germany and the United States may have tanks. Each tank negates the effects of two entrenched infantry. For example, If you�re attacking with 3 tanks then up to 6 defending entrenched infantry no longer fire preemptively (ignore step 4: defending infantry fire in step 5). In combat, rolling a 6 cause�s one tank to suffer a mechanical breakdown and the unit must retreat from combat. Entrenched infantry are still effected that combat round.
What is the reasoning behind the nations allowed? Only France, UK, and Germany had tanks. France and UK built over 2000 each, let’s round down to 4000 (but I think it was closer to 5). As I said at the beginning of this thread, Germany built 20. That’s 0.5% of the allied total. Not really worth mentioning, in terms of quantity.
Also, the German tank was considered an unsuccessful design and did not even appear until the 2nd quarter of 1918, which from an A&A game perspective is the second last turn at best. So it would be more appropriate historically to limit them to France and UK only…
However, that is not what the game is about. Existing A&A games allow completely ahistorical builds that are commonly used by players. Japanese and Italian mech inf jump to mind right away.
It also more then reasonable to assume that other powers had tank designs in the works (Russian Tsar tank, for example) that may well have appeared if production priorities were different. I’m sure several people at the time were more concerned with keeping higher artillery production a priority. I don’t think the capability to manufacture a tank was a problem for any of the powers.
I think we should take precedent from previous A&A titles and keep it simple. If you want a tank, build a tank. :)
