I enlisted in the US Navy in 1980 and was promised "free health care for life" if I retired from the military. In the late 80s, CHAMPUS was replaced by Tricare and different pricing structures were introduced. The latest proposal introduced in the Senate per military.com would make all levels of Tricare a pay service with increased deductibles.
