Quote from Magna:
I disagree and find statements like this strangely naive. Having served 3 years in the military my training and duty was to follow orders, and an army can't function any other way. That is exactly what those in the military will honorably do, whether it's fighting wars they may not believe in, or doing their duty anywhere in the world including here in the US. If soldiers are in a situation facing off with other Americans word may go around that they are confronting Communist sympathizers or Insurgents or maybe Terrorists who want to destroy their American way of life. Regardless, they will follow orders and do their duty, and anyone who thinks otherwise is an arm-chair quarterback who has never served.
During World War II Japanese American citizens were jailed and put into concentration camps here in the US. On May 4, 1970 at Kent State University an Ohio Army National Guard unit fired at students during an anti-war protest on campus, killing four and wounding nine. I'm sure the soldiers were taunted, felt threatened, maybe heard a loud pop or what they thought was a gun going off, and in volatile confrontational situations it's hard to determine what triggers things. But if you think soldiers won't abide by their training and follow orders even when dealing with Americans then you are sadly mistaken.
