How many terrorist attacks on US soil have been former military?

While precise statistics can vary, research indicates that a small percentage of terrorist attacks on U.S. soil have been committed by individuals with prior military experience. Studies have shown that around 5-10% of domestic terrorism cases involve former military personnel. However, it is important to note that the majority of veterans do not engage in terrorism, and the vast majority serve honorably. The motivations and backgrounds of terrorists can be complex and varied, making broad generalizations difficult.
