I don't disagree, but a young person does bring to the table speed and agility, but I guess its arguable if that is nearly as important as experience.
It's just interesting to see the differences and this article points them out as well:
China-Pakistan counter-terrorism drill continues CCTV News - CNTV English
Practical training is one of the biggest features of this year's exercise.
That is in a large part thanks to the Pakistani soldiers.
Most of them are in their mid-30s and some are well over 40. Many have over seven years of experience in fighting the Taliban and Al Qaeda.
The average age of their Chinese counterparts is 22. The Chinese soldiers' flexibility, discipline and technical proficiency impressed them greatly.
Captain Sher Khan, Pakistan Army, said, "Our trainings don't have that much skills involved. We don't have the speed that you are having. Our training is more operation-oriented. The soldiers were at the battlefield and they are coming right from the battlefield."
Our troops in the SSG range from 20s to 40s. The Chinese typically have troops of conscription age thus they are younger and mostly from the age group of 20-22.
We have to train the troops in roles that we foresee in a conflict. While calisthenics are important for increasing reaction time, close in combat (hand to hand etc.), special operations, and those too involving counter insurgency are very different things.
I think traditional Chinese flexibility, good work ethic and discipline is definitely something that we would benefit from. What we take to them in the form of our real experience in MOUT and FIBUA, Long range recce, mountain warfare, fieldcraft and sniper training would be invaluable without a doubt for our Chinese friends.
