During several games, since the latest update where they tweaked the helicopters for security forces. I have noticed that the Apache is apparently paper thin, and on several occasions has been shot down with only a couple of shots from an AK. The Apache is a heavily armored attack aircraft, with some armor points, mainly the cockpit, engines, and rotor areas being able to withstand up to 23mm anti aircraft fire. The Blackhawk, while not as armored, is still a workhorse and should also be able to withstand more than a few rounds from small arms fire. I understand they tweaked the dwell times for the helicopters, for more even game play, but the armor values really need to be looked at. The seem way too weak for their respective rotor-craft types.
