I was making a cool spreadsheet for bluebirds, but I have no idea what those three unmarked icons mean. I can guess that the last one is some sort of air infantry, but not paratroopers. I have no idea about the other two. The third one looks like a motorized anti-aircraft, but it only has a small vertical line in the center, so it doesn't make sense. It could be an unspecified weapon(WEAPONS/WEAPONS SYSTEM), but I don't know. It's weird. They don't seem to exist in APP-6 either (https://web.archive.org/web/20210621224739/https://litpolukrbrig.wp.mil.pl/u/APP-6D_JOINT_MILITARY_SYMBOLOGY._16_October_2017.pdf).Can someone identify them?
