I didn't say 200,000 people were trained every year, you did. What's the total volume of the military at any point in time per capital that are in maintenance roles? Whether that's the FC's who fix CIWS or the AS's who repair electrical issues on support equipment, everyone who uses tools to fix something.

Our squadron had almost 100 people in maintenance for 7-10 aircraft depending on mission requirement, that's not even counting I level who fixed the circuit boards and did soldering which we never even saw. If you saw maintenance to flight hours depicted on a spreadsheet you'd realize it's not remotely unrealistic for that many people to be in maintenance. Plus, planes and tanks make up less than half of the equipment that needs fixed, what about all the other vehicles infantry uses? The hundreds of ships the Navy uses? How many airman work on nuclear missiles and satellites?

You're blindspots in how many things need repaired are huge, and your assessment of how many people it takes to fix one plane or one tank is totally off.
