The Tactics of Survival Against a Terrorist Siege from Within

If a standing army is to be prepared against an enemy from outside its natural boundaries, that same army and its citizens at large must also be prepared in engaging a terrorist siege from within.  As all nations, nation-states and empires implode from within or get destroyed by invasion, or even become cowed into submission by external enemy forces, the most lethal force against a citizenry is that grim element of terror that comes from one’s own citizen neighbors. 
It should be understood the first signals of inter-war terrorism — mass civilian killings by a rampaging citizen targeting other citizens, often labeled by the military 'fratricidal' killings — can be a lone-wolf terrorist or a calculated terrorist organization that emerges from the citizenry itself, and not from outside the borders of a country, an indication of wide lethal terror that will manifest itself as the country implodes from within. Such a historical development one can currently observe in the United State in the early years of the 21st century. 
As the great Greek tactician Aineias wrote so brilliantly regarding preparedness within one’s own ‘city wall:’ “At no time, therefore, should you allow such plots to catch you off guard. When the Chians celebrate their festival of Dionysus and send magnificent processions to his altar, they first line the street leading to the Agora with plenty of army guards — no negligible deterrent to would-be revolutionaries."  
In other words, whether a mass of citizens are enjoying a musical concert in a lovely city auditorium during the day or night, whether they are athletes or ordinary citizens riding their bikes on a bike path, or even the most humble, hardworking people attending a religious service— there should be the most disciplined preparations for an individual or group terrorist attack. Those urban or rural officials who are in charge of such community situations should be tactically prepared to counter such attacks, while at the same time maintaining the safety of the leadership guarding the people at large.
When a manual of tactical response is finally developed, the military theorist should rely on factual evidence of terrorist violence in any given situation in order to combat its insidious nature, because an emotionally based response can only impede the developmental creativity of practical tactical repulsion within the environs of an internal threat.  
 The U.S. Department of Justice, for instance, studied active shooting against the American people occurring from 2000 to 2013 and found: “Study results also indicate that, of the 11 defined location categories, the majority of incidents—45.6% of the 160—occurred in an environment related to commerce. The second most common incident locations were in educational environments (24.4%), and the study results established that some of these incidents involved some of the highest casualty numbers”. 
 These statistics reveal that economic venues as well as educational institutions are in an egregiously vulnerable position, because of the main factors regarding class hatred, racial and ethnic tension, or manifestations of a psychological pathology that stems from an overall sociio-mental illness of the larger society. However, such terminology the F.B.I. would not use in their otherwise factual research, as they are serving the established government or regime of this historical epoch.  
The tactical procedures setting forth ways ordinary citizens can protect themselves from ‘home-grown’ terrorists remains an elusive  deterrent, unless the mass population resorts to neighborhood ':militias' policing their own communities, not unlike how the peoples of the ancient city-states had to respond to outward as well as internal 'civil violence' during the Peloponnesian War.  Concerning the recurrent  problem of easily attained weaponry  by those who desired to create insurrection, Aineias wrote: “Foresight is also necessary with regard to arms imported for sale and put on display in the Agora or in the shops and markets. If collected together there might be a great many (of them), so they must be placed out of reach of any would be revolutionaries”. 
The American progressive publication Mother Jones surveyed weaponry used by mass shooters and came up with these findings: “Weapons: Of the 143 guns possessed by the killers, more than three quarters were obtained legally. The arsenal included dozens of assault weapons and semi-automatic handguns with high-capacity magazines. Just as a perpetrator used a .40-caliber Glock to slaughter students in Red Lake, Minnesota, in 2005, so too did the one in Aurora, along with an AR-15 assault rifle, when blasting away at his victims in a darkened movie theater. In Newtown, Connecticut, the attacker wielded a .223 Bushmaster semi-automatic assault rifle as he massacred 20 school children and six adults”. 
Thus, we see from cold statistics created by human slaughter that these weapons are not in the hands of revolutionaries, but in the hands of  reactionary politically inspired killers with a pathological disorder just waiting to be triggered or corralled and manipulated by a regime harboring a  Fascist dictatorship, for instance, like what took place in Kiev during the Maidan protest movement in the Ukraine. And it was the citizenry of Donetsk and the Luhansk Oblast regions that took it upon themselves to protect themselves from the overall regime, a Fascist terror from Kiev.
It is my contention such a political and militant policing situation could indeed  take place in the United States, as the American people become tired and restless from the endless barrage of  terroristic mass killings.   
Now, the ultimate  political significance of these heinous  events must be faced, which is this: who are the main American terrorists creating  such catastrophic mass killings of the American people?  As one American internet researcher noted: "The Mother Jones database, which dates back to Aug. 20, 1982, counts 91 mass shootings. Of these, 50 were carried out by white men — hence, where Newsweek and other outlets got the statistic that 54 percent of mass shootings carried out since 1982 were done so by white men."
Grant Duwe, author of Mass Murder in the United States: A History, considered a leading scholarly book on the subject, has long criticized Mother Jones’ accounting. "The main concern is an underreporting problem that gets worse the farther back in time we go," Duwe told PolitiFact. "This creates problems when it comes to drawing conclusions about trends in the prevalence of mass public shootings."
Nevertheless, Duwe claims his own research dating back to 1900 corroborates that white men have committed more mass shootings than any other group, though he believes white men make up an even larger share than the Mother Jones data show”.
What is occurring in the United State, then,  is an interstate terrorist war inflicted upon Americans by other Americans, with  the majority of these terrorists being White American males. The mass killings of ordinary working class or rural people who perished senselessly in Sutherland Spring, Texas on a Sunday morning in November, as they were participating in religious ceremony, is an indication of a more vigorous tactical reconsideration that must be studied by modern military theorists in such an historic era that has not similarly been seen since the cruel internal civil wars which took place in the city states during the Peloponnesian War.
