Well, maybe the best rifles
(Sako
), and all that beautiful hunting ground, so maybe the Finnish Army is starting off with a little bit of an unfair advantage in the recruit pool that it can draw upon.
For the PLA infantry, marksmanship depends upon a few factors. The first is that they receive only 2 month's basic training and no infantry trade training before being sent to their unit where they receive on-the-job-training, and after the first four months of that, they are considered "trained". Still, as long as the leadership is competent and training resources sufficient, PLA infantry should be reasonably proficient at weapons handling and shooting with rifles out to 300 metres (the generally accepted minimum standard worldwide for infantry).
Given that PLA soldiers can only serve two years before they are automatically demobilized (unless they are subsequently accepted for 1-3 months NCO training), they have only a short time to get their skills up to a high standard, and about half of the training year in a PLA infantry unit is concentrated upon unit, not individual training. The other half, of course, the unit devotes to providing 2 months' basic training (or detaching its officers and NCOs from the unit to do so) for new recruits and then spending 4 more months on in-unit individual training for those new recruits. There's not a lot of time for troops to achieve high marksmanship levels (except fot the naturally talented).
Similar problems exist in the US Army. Infantry there receive only 13-14 weeks' training before being sent to their unit, which then has to spend part of its time training the new infantry recruits up to standard (if it has time and resources to do so.) In their 9th week of basic training, US Army recruits only have to qualify out to 100 metres with a rifle
. Not exactly cutting-edge standards. So whatever is missed in the final 4-5 weeks of infantry training that US Army infantry receive, the units the troops are sent to have to make up the difference, if they can. The main difference is that the US Army doesn't automatically discharge its troops after only 2 years' service.
So the regular PLA infantry should have reasonable marksmanship standards, especially compared to US Army infantry, but they shouldn't be expected to necessarily have the same marksmanship and weapons handling standards of European-style professional armies (as opposed to short-service conscript armies).
