It's not really that surprising. The government has historically given veterans the shaft.
In 1932, there was this group called the Bonus Army, which was comprised of WWI veterans, who marched on D.C. wanting the government to follow through on the Adjusted Service Certificate Law, which would have helped the veterans and their families.
How did the government respond? The Army came in basically massacred them due to a technicality in the Posse Comitatus Act (this act prohibits the Military and National Guard from being used in a law enforcement capacity under Federal authority, EXCEPT when expressly authorized by the Constitution or Congress), since Washington D.C is federal property that is governed by Congress.
