Irl, all special military/gov't agency units have training facilities (and pre-screening processes) they use to make sure their operators are well prepared to carry heavy stuff (like each other) and shoot well and handle casualties etc., and also send their operators to places like
https://shawshooting.com/ for specific skills training from people who do nothing else professionally, every day.
As is, in OXCE you need to either fire your low-performers or do counter-intuitive things like make them start with something in their hands to throw a few times to make their Strength go up, and choose weapons that they can hit with without killing an enemy to make their Firing Accuracy go up.
The X-Com Files has a gym facility that seems to work more or less well, though I only played XCF for a few weeks. If you would like OXCE to be slightly more similar to irl organizations, I recommend the following:
1. Enabling a single gym (+shooting training) facility, or two separate base facilities.
2. Allow substandard personnel to develop their some few skills only in these facilities up to a certain point but no further, and/or allow further improvement at greater cost in time invested (?).
Apologies if this has likely been discussed before, I fail with the forum search function for OXCE. I just thought I'd add my very minor irl experience.
