This was extremely demoralising, and an important part of the romans success.
But zombies do not get demoralized, they just keep piling up, they are more like a wave of meat than an army.
The weight alone would break the romans formation.
No, that style of shield wall was designed to hold up to a lot of pressure. They trained to do a full formation shield press....think of 50 men in a row pressing their shield into the curved edges of the shield belonging to the man in front of them, kind of like tug of war with a rope in reverse.
The gladius would be quite useful for the front rank....either stabbing downward into the head of a zed trying to crawl under the shield wall, or to lop off the hands or fingers of zeds trying to grip the top of the shield. Spearmen from 3 or more ranks back would be stabbing zeds in the head while archers and slingmen rained head piercing objects down on the hoard.
If your still don't like the Roman/Greek soldiers for this, then an alternate would be:
Thai Elephant soldiers...
Armored elephants trained to fight.
The elephant trainer armored, riding along with armored soldiers in a basket on the elephants back armed with log spears, bows, and cavalry swords.
