In this case her Army experience is going to be the thing to focus on. She could look for small government contractors who need tech work (because they’re government, the tech lags cutting edge which is good for her) and subject matter expert work. If she can do both it’s a big win.
I used to work for AEPCO a federal contractor. It was US Army contract work at an Army base for logistics. It was 1996 and they used all kinds of legacy systems. I was in the US Army ROTC which helped learn military terms. But I upsized databases from DBase Lotus 123 Clipper to MS Access and SQL Server and Oracle PL SQL. This skill of converting data from legacy systems to modern ones pays a lot.
I'd agree, but for reason that some HR organizations are set up to hire military veterans.
You can do a Google search for "companies hiring ex military", and Google will pop up a job search based on military occupation codes. Or you can look around websites dedicated to it.
Or a smaller company that ether supplies defense contractors or takes subcontracts. A lot of these very small companies are robustly staffed with ex military already and may not exhibit the ageism you’ll find in the average tech company.
