In a number of the militaries of less wealthy countries, a soldier's time is cheaper than new vehicles and there aren't sufficient threats to justify spending large sums of money on the latest shiny toys. There are M8 Greyhounds still serving in multiple Latin American forces, while the last M4 Sherman tanks were retired in 2018 and Paraguay might still have some M3 Stuarts in service (Uruguay retired theirs in 1999). As far as I know, M3 half-tracks are still in service in Mexico. About 15 years newer but still "obsolete," there are hundreds of M60 tanks still in service, to the point that Raytheon and Leonardo have both introduced SLEP packages within the last 5 years, while Taiwan implemented an Elbit SLEP in 2019. There's plenty of old stuff either still trucking along in active service with second (or third, or fourth) users or in reserve to be recalled if there's a big enough war to need fast expansion of a military.
