German army arguebly has the toughest training in the world, if any of u ever get a chance to go to mountain warfare school in germany, u won't doubt me.
Considering the fact that the Germans train their mountain warfare troops with Norwegian special forces, I find that an odd comment.
I'd question whether Germany does have the toughest training in the world as well. The quality of the training is impacted upon by various issues:
experienced battle tested officer cohort
volunteer or conscripted army
whether the nation is in a state of conflict or whether they have a benign military environment
frequency of combat to finesse doctrine
when their current warfighting doctrine was last updated and when it was last actioned
how often they do dissimilar combat training.
on the basis of the above, I can think of 5 other countries which rate higher by a considerable margin.
For sheer quality of training, I'd argue that the British Army has the best Infantry trg in the world - the most diverse battle testing and the most diverse experience out of any nation in the last 250-300 years.
No other nation comes remotely close to their win ratio.
