Hardy/Very Hardy unit attributes?

[HalfThere]

I've seen these in the unit attribute line of export_descr_units.txt

The explanation at the top doesn't detail these attributes, does anyone know what effect they have.

[Ahmose]

It determines the unit ability to recover faster from tiring during march or run. In the past I thought that, for example, a unit with hardy attribute will not tire faster than a normal unit. But I did some tests with units and found that every unit whatever it has, will tire in the same time as a normal one. The difference here is how it fast will recover and being fresh again.

yes, tested that too, its true.
shouldnt be really, as different units carry different stuff, and/or move around more in general...i mean afterall an armoured horse should tire a little faster than a light one, even when it cant run quite as fast...or when having to drag a heavy chariot, as oppossed to a light one, and better training or experience doesnt affect stamina...the recovery aspect is still great though...as i dont really mind having to fight longer battles, so having a few very hardy units who can rest up faster and attack the enemy who is still catching their breath is useful...not as many losses, well not for your army anyway.

Some units being highly trained and with a higher morale recover faster and can fight longer. History has proven this to us.
