I know that when I joined up in 1997 a lot of those bonuses simply disappeared if you didn't keep ahold of your original paperwork. Sometimes they had a lot of hidden clauses, so you could lose the bonus for a minor infraction. Or, the bonus was really part of your pay and the full amount would be paid out after if you actually completed 8 years instead of the 2-4 year commitment you started on.

All I know is I personally ended up permanently disabled at 18 and fought with the VA until 2019 to get my disability compensation. Which they only paid me back pay from 2009 instead of from the date of disability in 1997.

Getting money from the government takes a long time. The people downwind of the Atomic test sites have been fighting 50+ years for the full payments from being irradiated during the 50's.

But hey, joining the military is a good job if you aren't stupid and taking a combat MOS when you could have a steady non-combat job with perks. Right now the Commissary benefits for cheap food is worth it with how food prices have been going.
