But individual equipments could help to improve the survival rate of the soldiers... which is a big deal (to that soldier in question, at least).all the money is being concentrated on big toys now, no need to waste them on individual equipments
I'm not saying that the older equipment is useless or not useful for training raw recruits. I'm just thinking all military equipment has a certain shelf life for example the spring and barrels of small arms. These parts need to be replaced after significant usage.But individual equipments could help to improve the survival rate of the soldiers... which is a big deal (to that soldier in question, at least).
However I agreed that you do not need top notch equipment and weapons to train the soldiers and it is certainly kind of wasteful to provide every single troop with very advance and good equipment when most would not see any actions throughout their service life or even be deployed in very hostile environment.
Anyway, China had a huge stock of 7.62mm rounds, Type 81 rifles and older infantry equipments that are still effective in today's standard, so really no need to change these for second line soldiers.
