The United States military has members in a number of different countries. Sometimes, they require assistance that does not come through the military itself. There are American corporations who will send workers overseas to help the military on their bases. These can be laborers for construction, electricians, computer experts, medical personnel and a number of others as well. Just because they are helping out on a military base does not mean they get military benefits though. When a corporation sends someone overseas, it is their responsibility to make sure that the person has Defense Base Act insurance.
This is not up to the independent contractors but rather the corporations that they are employed under. They must make sure that every person working on an American military base in another country has the proper insurance in case something would happen to them. For example, if a contractor is working at a remote base in Afghanistan and is injured in a roadside bombing, this insurance would help with the medical treatments that would be required. If the worker is injured to the point where he is not able to return to duty, then this insurance also helps replace his income since he is no longer able to perform his work duties.
One sad fact about workers who go to another country to do contract work is that not every one of them returns home. They are often in hostile environments, and it is entirely possible that one can be injured or even killed. For the ones who are killed, this insurance often contains benefits for the families left back home. Death benefits can be left for spouses as well as children.
