Higher levels of gun combat skill might incude the ability to do your own reloads. Something I hope you learn somewhere safe and not through trial and error experience.
Higher levels of gun combat skill can include knowledge of the effects of things like different atmosphere densities on ballistics. Something you could possibly be taught in a classroom, at a gun range that simulated a variety of atmospheres, or again learn via trial and error experience. Hope your unit doesn't get overrun while they are trying to figure out why shots are off.
You can learn how to point a gun and shoot, but there's a limit to how far that can take you. Similarly for other skills; nothing beats hands-on experience. Or lets talk about another skill, like Driving. You can learn how to drive and it probably won't take that long, maybe half a dozen lessons or more or less, depending on aptitude. But that will only cover the basics. To actually grow comfortable driving, you need to get behind the wheel and drive. And to do that constantly.
Training and schooling can include hands on experience. There are advanced driving schools and there is a difference between getting behind the wheel by ones self and having a highly skilled instructor there. The driving school instructor can have you try maneuvers in a safe environment and give instruction on how to prevent as well as what to do if something happens. Also, higher levels of drive should also cover some additional maintenance and repair knowledge. Often skills can overlap so this doesn't have to be learned as a mechanic skill which is knowing mechanics of all types, not just vehicles.
and these are difficult to learn by experience alone - which is why real world armies use a series of schools to improve their soldiers' skills instead of relying on experience alone.
Yes, but once you graduate from school you don't have to keep going back to it to learn more; it's assumed you learn enough to carry you through to your assignment. Training can only take you so far.
Soldiers, especially as their responsibilities increase, which is normal as soldiers gain experience 'in the field', are assigned additional, more advanced training. For those who have not gained enough 'experience' to advance to the next school, often they have to repeat the same school, or a shorter version is required on a regular basis as refresher training.
Anything higher than 0 represents experience, not more training. I think any advancement system that gets implemented ought to take that as the focus IMO.
This is true for some skills, but in my view not for most of them. No mat-
ter how much experience a Medic-1 will have, experience alone will not
make him a skilled surgeon.
Are you kidding?
I don't think he's kidding. I agree. Even highly skilled professionals read trade magazines, go to conferences, and attend training on currently unknown equipment or procedures. Hopefully doctors don't just experiment on their patients to gain experience.
There's a limit to what you can learn in a classroom.
Most more advanced training is a combination of 'classroom' and 'hands on' training. Of course, 'practice makes perfect' is also true which i think is your point, actual real world experience is often needed before you can go off and just take the next higher level of training. Personally, I believe at all levels, without some form of training (classroom, online, reading trade journals, reading 'papers' written by others in your field, simulators, and so on) it will take considerably longer, and you will be much more apt to errors as you attempt to learn the higher level things through trial and error in real life situations. How long will this trial and ERROR person be able to stay credible within their career field. Eventually they would probably get fired and have trouble finding work.
Jumping to another skill, Athletics(co-ordination), I do believe the majority of Olympic level athletes have coaches that give instruction. Professional football (US) players have coaches that give instruction, determine the proper exercises and practice needed for their players to improve. Players review game film of their opponents, and sit through 'classes' to go over the play book. A new NFL player shouldn't just say "hey, I learned everything I need to know in college so I can just show up when it's game time."
