Yes it is from "MAKE WAR NOT LOVE".
You got two commanders for free if you had played CoH2 that weekend.
German Commander: Close Air Support / Soviet Commander: Advanced Warfare Tactics
After that weekend Relic put them into the steam-shop for purchasing, but deleted them after a while. People who participated in MWNL or purchased it via Steam could keep it.
I remember a thread on the official CoH2-forum regarding the German Commander Close Air Support, where Relics Developer Eagleheart pointed out that Relic does not have any plans to bring it back to the shop yet.
