This is what you would do if you free up a lot of free time for efficiency? Improved skills, went to training? Fuck the two. Technique to chase - pleasure is expensive: GSM, spare parts, ammunition, logistics, etc. And even the technique is designed in the army for imbeciles (because the average level of the soldier is), and without the technique there is nothing to improve at all: the AC and the MPL-50 shoulder - there 4-year-olds will cope. So what would the soldiers do?

Western option: If a soldier is unfit to do, he improves combat skills beyond the norm, lacks material and technical support, studies theory and uses various trainers and simulators.
Eastern option: If a soldier is a nephig to do, he trains the skills of close combat and survival in different conditions, because this does not require a flat count of niphig.
Ancient, outdated option: If the Legionaries do not, they build walls, roads and other useful infrastructure.
If you look for more, you can find a lot of useful activities, instead of learning in a few weeks, and then engaging in erotic agriculture for a year or more.
