If private security agents are subject to prosecution in the U.S. courts, why would the U.S. want to hire any of these private security forces?

The United States may hire private security forces because military and government personnel cannot meet every security need in a war zone. Private agents can provide additional trained personnel for tasks such as protecting facilities and officials, even though they may still be subject to prosecution in U.S. courts. Thus, the best answer is that there are not enough well-trained personnel for all security requirements in war zones.
