Is money earned from an additional military job, whose duties are not performed, unlawful (haram), knowing that it is affiliated with the government, and the primary civilian job is also affiliated with the government and I am still performing it?

An employee must abide by the terms of their job. If they do not perform their military duties according to regulations, they do not deserve the wage and must return the money to the employer. This is because acquiring public funds unlawfully warrants the Fire on the Day of Judgment.

However, it is permissible for the employee to receive their salary if the official has exempted them from their job duties and was authorized to do so. A private employee is entitled to their salary by making themselves available for work, even if they are not utilized.
