ATK: Units base damage
CB: Charge Bonus
TD: Total Defense (combination of armor, defensive skill, shields etc.)
ARM. Armor strength

Desert Axemen ATK: 10 CB: 5 TD: 18 ARM: 11
Armoured Hoplite: ATK: 9 CB: 7 TD: 22 ARM: 11
Sacred Band: ATK: 12 CB: 8 TD: 23 ARM: 11

Check the armour value. Yes, both Sacred Bands & Armoured Hoplites have higher TD value, but that bare-chested not-armoured at all Desert Axemen have same armour value as Armoured Hoplites I call a tad overpowered.

And as chemchok said, Egypt gets strong each game, so there must be some imbalance.

If devs say that Egyptian units had to be "tuned up" to face the Romans, why didnt they tune up the Gauls and Britons at the same time? They were easy to take out!
