Where’s the advantage? Most Fed employees get 1% of their highest three years salary for every year they put in. So, to get that “only 50%” you claim is so horrible, a civilian FedGov employee would have to work nearly 50 years. Why not educate yourself before posting inanities.

The military 50% at 20 is on “base pay” only. Numerous military types whether officer or NCO, get maxed out on pay at mid paygrades like E-6, 7, and officers who are O-3,4.
Now lets look at this 1% per year and let’s be truthful about GS12 or so types with 30 years. Try about 56.25 and 42 years would yield 80% or more. Lets look at TSP and FEHB. Tell me that the military Tricare beats the non Obamacare plans that every Congress critter gets, too. My BIL left as a GS 14 to be VP of a major aerospace Corp. He owns his own defense contracting Corp. Men I served with, like a fellow CPT, retired from the CIA 6-8 years back. He was head of South America. He had well over 40 as he was medically retired due to wounds. I knew an SF Major who went to the State Dept in Vietnam. He was head of I Corps in Vietnam. He is so poor.
