We are not talking about militia, which we already have. We are here talking about individuals not organized or formerly trained being armed.
I see. Like a rushed militia. This is bad formation. Poor discipline, even if organised. They basically run like civilians around, while getting slaughtered. Even American civilians' mob, has more experience in shooting and gun maintenance, even if they miss basic military training.
However basic militia is civilians with guns + training. In past it used to be just peasants with forks and not much training at all.
Militia is not officially military and militia is not being taken under consideration as part of military forces. Militia and Army Reserve in USA form National Guard and militia can not serve outside their state. Florida used to have militia coast guard fleet, while Texas has militia combat air wing (F16 I think).
The covert elements can move undetected, allowing them to establish an overwhelming local superiority at any place of their choosing. Then reinforcements can pour in from the main force and take strategic ground.
Covert element have harder time to move undetected, because:
1. Militia has more manpower and better equipment then Police to detect and respond to accidents.
2. Militia has intelligence gathering training and issued sat-phones to pass that intel up in the chain of command really fast.
3. Aliens do stick out of the crowd of familiar locals, who will be watching them anyhow. Even out of curiosity.
4. Part of militia training, as territorial defense force, is protection of vital local infrastructure.
5. Reinforcements can pour, if they are regular army and organized in attacking spear, but even then Militia will provide mines and other "surprises", slowing the reinforcement's assault.
6. If reinforcements are irregulars, like commandos, paratroopers or mechanized infantry without significant artillery support, then they can be ambushed, surrounded and kept under guard by militia force until army units will find time to take care about the issue, or even SWAT teams from police.
Not when the attackers can mover undetected by disguising themselves *as* civilians.
However not as LOCAL civilians, because militia will be locals and locals always keep eye on moving through civilians, who are not local. Human nature. Plus on behalf of militia also some training for spotting, tracing, marking, signaling. The exceptions could be, if there are some international events, then there could be huge inflow of non-local civilians. However militia receives training in guarding strategical infrastructure and if someone is to spot covert operators causing trouble, then militia with their training and equipment.
Where there is a will there is a way. The more dangerous you make the civilian population to the occupiers, the more extreme is their response; recall the crucial element of organization means that even if armed the civilians will still not be able to actually resist the response. Once you have incarcerated or killed the entire civilian population, then you can disarm them and the problem goes away as it were. If I leave everyone alone however, then they can hide their weapons in their homes and then suddenly rise up in an organized way to attack you.
Yup. Who needs nuclear weapons, with such deterrent? If enemy knows that for every house, every road, ever tree they gonna pay with blood and dead soldiers then they think twice before attacking. After all equipment and training of elite soldier costs a lot. Furthermore nuclear bombs costs fortune and to clean a path through such armed to teeth civilians territory, it becomes cost prohibitive. Not to mention dangers from nuclear fallout. I think it is called a Pyrrhic victory. I think USA got something like that in Somalia a while ago. Mines bite.
There is no such thing as a totalitarian regime, the whole phrase was something made up by some Cold War propagandist, I think and means nothing that is not incorporated by other older perjorative terms like 'tyranny', which are also invalid in my view. You cannot calm down an enraged person with a gun when the enraged person has a gun themselves. If nobody is armed then you can physically restrain the unarmed person, but nobody can physically restrain an armed person; they must be fought by another armed person and the outcome must result in bloodshed.
Definition of totalitarianism is in Wikipedia.
In basic. The thing is that if bad gets really bad and shootout starts, then whomever caused it, is stopped dead in track asap.
In advanced. Furthermore there is no need for rage with organized criminals, who can import/export drugs, but wouldn't few guns? Any businessmen is their legit target then for "protection" scam. You get faulty capitalism. When they use those on politicians and administration workers, you get corruption and your parliament is calling hearing after hearing, where other politicians have to leave their testimonies. This is how democracy rots and falls apart. Then you get patriots trying to rescue everything from falling apart from what it used to be and you get a dictatorship. Hopefully benevolent, but still a regime. Often military. More often right wing, then left wing due corruption reasons. It always goes to hell. Though countries like South Korea got lucky, got back to democracy and functional capitalism again. However South Korean secret anti-communist police was inhumane and absolutely deprived of any slightest sign of Humanitarianism.
That is basically what it is about. It just so happens that every one of my points which applies in a fully-developed Dwarf Fortress also applies in real-life.
However DF will have magic, so developers can get around Real Life issues. A MAGIC!
