Which of the following is NOT a main component of TRICARE?

TRICARE is comprised of several key programs designed to provide health care benefits to eligible military members, retirees, and their families. The main components include TRICARE Prime, which is a managed care option providing a primary care manager, TRICARE Select, which is a fee-for-service option allowing beneficiaries to choose their providers, and TRICARE for Life, which serves as a wrap-around coverage for Medicare-eligible beneficiaries.

TRICARE Gold, on the other hand, is not a recognized program within the TRICARE system. It has never been a part of the TRICARE offerings, making it the correct answer for this question. Understanding the current components of TRICARE is crucial for anyone assessing their health care options under military health benefits.
