The majority of service members kicked out over their refusal to get vaccinated received general discharges. With a general discharge, service members lose all educational benefits, reemployment rights, and civil service retirement credit.

Hayden Robichaux, donor relations coordinator for the Mighty Oaks Foundation, is one such service member. He had to build a career in the Marine Corps. He spent his initial two years serving as the military equivalent of a firefighter. But life as a Marine was interrupted by Secretary of Defense Lloyd Austin's announcement of a COVID-19 vaccine mandate in August 2021, he told The Epoch Times.

Robichaux refused the vaccine and sought religious exemption.

"But it seemed like everybody who sought religious exemption was denied," he said. Months later, a leaked June 2021 memo by the Pentagon watchdog revealed the department may have been violating standards in its process of denying religious exemption requests for the COVID-19 vaccine.

In addition to his religious conviction against the vaccine, he took objection to the fact that the only vaccines offered to service members at the time were labeled as authorized for emergency use, rather than having full FDA approval. This argument stems from the wording of the Pentagon's vaccine mandate, which covers "COVID-19 vaccines that receive full licensure from the Food and Drug Administration (FDA), in accordance with FDA-approved labeling and guidance." Robichaux and others believe that this means the mandate did not apply to any vaccines issued under emergency use authorization (EUA), such as the Pfizer-BioNTech vaccine.

They argue that the military mainly offered service members EUA Pfizer-BioNTech vaccine, rather than the FDA-approved Cominarty vaccine, and thus could not compel personnel to take them. They also argued that a Pentagon policy that says the Cominarty and EUA Pfizer-BioNTech vaccines are interchangeable was illegal.
