I served for a total of seven years, but I understood the meaning of what was happening a month later. Everyone thinks about being healthy. The meaning of army life activity is not to do everything effectively, but to work day and night almost without rest. 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. The technique is calculated.
In the army on imbeciles (because the average level of the soldier is), and without the equipment there is nothing to improve: the AC and the MPL-50 shoulder - there 4-year-old children will cope. So what would the soldiers do? Based on the indicated average. "As long as a soldier stands in service, he cannot commit a war crime"

It is...

Physicism, the study of the history of wars, tactical, partisan, defensive, offensive and other actions, crafted substrats of Vietnam/Afghanistan/Chechnya (strings, holes of the type of Vietnamese souvenir, forgotten and abandoned ammunition with trothyl instead of powder, etc.) and their detection / disposal - all this is done for free. But the brain needs to be turned on, yes.
