Yes, it's CM:BO. Like most PC wargames, I never liked it much, because it simulated a wargame rather than war ie micromanagement, moving individual 'pieces' around rather than giving orders to AI commanders at the level below who would then use AI SOPs to execute them. A sort of PC way of doing what the ground-breaking Wargames Research Group revised 1925-50 rules did, latter applied to their Cold War set. So far, of the PC wargames I've tried, only GT:OS does a decent job of that.
