I play the HBG Global 36/39 version of Global Axis and Allies. (Look away SS before your eyes burn :-) ) I have several of the additional pieces they make including light tanks, SPG, and tank destroyers for all nations. One of the problems with these pieces is their increase cost does not justify their purchase over the basic units. (This is true in the SPG and TD case.) I was looking at ways to improve the use of these units. I was thinking of trying the following rule and would like feedback.
“Blitz Support” - any unit tagged with this ability can participate in a blitz but can not initiate a blitz. A unit with blitz support can pair with a blitzing armor at a 1:1 basis. This pairing does not interfere with that armor ability to pair with a mechanized. Support units based on their use during a blitz must be taken last as casualties.
Lt armor, SPG, tank destroyers, and armored cars would all be listed as blitz support. My biggest concern was adding attrition style kills (armored cars cost 3 IPP same as INF) to a blitzing stack so I included a caveat that they cannot be taken as casualties until the end of combat. However this allows 2 Medium tanks to blitz with a 6 unit force now which makes defense in depth issues in Russia much more complicated. I am concern this rule could make a Russian defense much more difficult.
I think I will introduce this rule at our next game and see if the group wants to try it, however I would also like feedback if it is a good idea or completely unbalancing.
