It is situational because depending upon the location, there will be automatic fatigue and disruption. Think of the malarial zone or the blizzard area. But usually I try to keep the numbers below 20 if at all possible but sometimes when the enemy is about to crack, I just attack with every unit. Otherwise you can rest some, including on the defense in Reserve mode which will only go active if they can prevent the loss of the battle and thus the hex. While attacking and rotating your units to Reserve mode to rest them just make sure that there is no pursuit in case you win so your units don't get strung out chasing the enemy into the next hex - unless you actually want that to happen.

Good advice from RJ. You can imagine the fatigue number as a % hit on the effectiveness of the unit's AV. So if fatigue is 15% and you imagine you want your Regiment to attack the enemy, does it still have enough effective AV? You also have to factor in how much the enemy might be degraded by previous fighting, air attacks or naval bombardment and the supply situation on both sides. You can get a hint of the enemy fatigue levels by their disablements in previous fighting. The progression of ground unit damage goes: fatigue->disruption->disablement->destruction.

And note that support squads are usually the first squads to be affected. Soldiers fight from foxholes and trenches and other cover. Support units have above-ground locations (like a tent kitchen or in trucks used for supply). Guess which will be caught by the sudden arrival of artillery shells.
