I've talked on here in the past about how crazy it is that some of my customers had huge financial systems that were written in COBOL, quietly still plugging away.
The most important of which is a system which processes billions of dollars of transactions a day, and has done so since the early 70's (when they purchased the what was then off-the-shelf software). You can imagine what a maintenance nightmare it must be (both because it's old, very important, and written in a programming language which predates the cotton gin).
Assuming that they can't just rewrite the system (which might be a reality), they can certainly sit down a bunch of developers and have them learn COBOL. COBOL isn't even a particularly difficult language, we were writing pretty decently-sized programs after a few months in high school (and if the system is that old, it's probably not even using any fancy language features).
If only the military had some means by which they could take people without past exposure to some skillset and train them to be competent at that skillset. Maybe part of that training could involve having to climb over a wall, or some sort of rope course.
