Lol. It's obvious that some active duty soldiers (in professional armies) would desert, some would probably not. What would start happening would probably be that service personell (including police officers) would bring their families and friends to safer-than-average-"safe zones". National guard units (and international counterparts) would probably shine because of the locality. In my country of origin, many former active-duty soldiers join national security forces reserves. Weapons and equipment for these units exist close-by, and you'd probably start seeing a response a few hours after such an order has been received. People (preppers) seem to completely disregard human capability for selflessness in military contexts. It's as ridiculous as that "Max Brooks" World War Z's episode "Battle of jonkers" where soldiers suddenly panics, you know, stress training is an integral part of modern day training. Human wave tactics stopped being effective a long time ago you know, and not just because of "shock and awe". In my very brief time in the army, we learned to shoot from a prone position with enough accuracy to hit three consecutive shots within approximately a nickel (from 50m) within a few hours of practice and shooting with iirc 3cm dispersion from 100m (well within "head" territory). So overrunning won't happen in that regard, even if transmission is airborne. At the same time soldiers are people, and most wouldn't abide by totalitarian measures (that are too extreme), and would most likely simply not enforce it. Quite the opposite, there are incentive for some to stay and protect their country/home through their service, seriously, how do you think wars have been thought throughout the years? There's always been risk, and hurt to family and friends during wartime. Thinking that everyone would so quickly desert is just misleading. And even in those cases, plenty (if not almost everyone) would join up with local national security forces on site anyway (where applicable). P.S. Like Serrates says, how do you think militaries work? Seriously guys? You think the training and uniform makes you a mindless drone with no issues at all with killing fellow citizens on a whim? . And this is why general conscription isn't the worst idea in the world, since people actually get an insight into reality.
