German Panzer Tactics in WWII Online
www.hq.wwiionline.com/articles/panzer_tactics.shtml gives a brief
introduction to German WWII panzer tactics. Intended for the game WWII
Online, but the material covered should apply to Tank Battle too.
There is however a short section on Supply which (at least not initially)
will be a factor in TB.
Panzer Vorwärts! Aber mit Verstand!
www.hq.wwiionline.com/articles/armor_forward.shtml Another article
intended for the WWII Online game. 30 simple lessions for the
German Panzers, based on experience from the war with the Soviets.
The lessions should be a guideline in the design to make sure that the
options provided to the player are somewhat plausible.
Panzer Page - The illustrated history of German tanks in
WWII
www.militarygameronline.com/Panzer/panzerpage.html has lots and lots
of pictures and short texts on German panzers.
