Role of hunting in military training.

[Giannis K. Hoplite]

At least it is directly connected with throwing a javelin accurately in a moving target,or using a bow. Given that boars and bears and even lions were popular targets,avoiding a fast moving animal with more strenth than you would resemble a weapon perhaps. And most importantly it would make a man more steady in dangerous situations. One more usage may had been that some times hunters went armoured like in war. Running,hiding,exercising hard with your panoply on is on itself a great aid.
Perhaps it wasn't much of an aid in a pitched mass fight,but war is not only tightly packed men who offer their body free to an enemy spear. Obviously Spartans gave great importance in being able to survive alone or to be able to hide.So it must have had some relation to ancient war. Not to mention that a hunter has to be capable of finding traces of animals(could be men) and finding their way in unknown land.
I suppose it is unecessary to mention all the ways hunting mounted can benefit fighting as cavalry.
