Yeah after closer inspection the heritage Foundation document is pure trash. While the neighborhood analysis is flawed, when combined with other data it paints a picture. Military recruits are more likely to come from the southern states, more likely to have grown up in wealthier neighborhoods, and no more racially diverse than the general population. They aren't exactly ripe for communist radicalisation. That doesn't mean Americans shouldn't try, they should absolutely try to radicalise the troops and get them on their side. But at the same time Americans should not be surprised if the troops turned on them in the same way the police and DHS have, and definitely should have other plans than just radicalising the troops.
