Hitting HQ should not take out all radar or dar bars, if the stated purpose of this game is to promote air combat that is, it's just dumb. Also why is there no radar anywhere near the HQ, if the HQ is so important it should be surrounded with radar. Each of the strats should be covered with radar. Every approach to the HQ should have radar. Let the downed HQ represent the communication and coordination of radar intelligence, you lose the ability to see friend or foe except for your local sector and DarBar in all sectors should remain. My understanding of the DarBar is that it always represented the local population of countrymen, reporting or sighting enemy aircraft. Like the aircraft spotters actually did in England and Europe and even in the United States during the war. Those reports were collected locally and passed along up the chain of command to a central reporting /dispatch that than directed intercepts back down through the chain of command. Even when the centers took direct damage they were seldom out of action for very long and the chain of command just shifted its duty to another center. The field spotters continued to do their jobs and report aircraft locations (darbar) to the new center and the chain of command continued to function. Within AH if the HQ is knocked out it's as if all field spotters were knocked out as well as the entire chain of command and that's just not right.
