Hawk Wargames has updated its Command Cards, which can be downloaded as a pdf for free, or purchased on the the Dropzone Commander Website. Personally I like how some of the cards expand into the realm of protecting or boosting aircraft. I think its a great addition, although none of this will be ultimately be game changing.
Here you can check out the new Command Card changes. These cards replace the current cards they are named for.
