A Question for Glynn about Fatigue

[Gordons HQ]

Hi Glynn, I am playing the standard campaign game of Market Garden 44 and I wonder if you could throw some light on the fatigue factor in the game.
I've played many other games PzC games but I have never seen such high an accumulation of fatigue in such a short space of time. It seems the Allied paras only have to open fire and get a huge amount of fatigue, likewise if they assault they can go from none to very high levels instantly.
Perhaps there is nothing special here but I don't seem to remember this happeneing in for instance in Normandy 44, or perhaps this is indeed a special circumstance for this campaign.
I looked in the campaign notes but could not find a solution so perhaps you could help explain if there is something unusual about this particular campaign.
My oppenent has also mentioned high levels of fatigue amongst some of his Axis units so maybe it's general to this game.
I appreciate any light you could throw on the subject as it seems a bit baffling to me.

Cheers,
Gordon
