Rome Total War Barbarian Invasion Units

In Rome: Total War - Barbarian Invasion , the unit landscape shifts from the early-Republic legions of the base game to a gritty, high-defense era of heavily armored infantry and devastating "shock" cavalry. This expansion introduces distinct mechanics like Shield Walls and Schiltroms, which make high-tier units significantly harder to break than in the original game. Key Unit Features & Mechanics

High Defense & Armor: Units generally have much higher defense stats than their base-game counterparts, making battles longer and reducing the frequency of instant routs. Formations:

Shield Wall: Exclusive to elite infantry (e.g., Auxilia Palatina, Chosen Swordsmen); it creates a dense, impenetrable front that provides a massive defense bonus.

Schiltrom: A circular defensive formation for spearmen that is highly effective against cavalry charges from any direction. rome total war barbarian invasion units

Horde Units: Barbarian factions that lose all settlements become a "Horde," spawning massive stacks of varied units that travel as a unified, migrating nation. Special Abilities:

Swimming: Some units can swim across rivers, allowing for flanking maneuvers during bridge battles.

Pre-Charge Missiles: Many "barbarian" infantry units now throw javelins or axes before charging, a trait previously unique to the Roman Pilum. Notable Units by Faction Type 🏛️ Roman Empires (Western & Eastern) In Rome: Total War - Barbarian Invasion ,

The late-Roman military focuses on heavy defensive lines and professional professional core units.

Berbers, Saracens, Armenia

Desert Raiders: Fast light infantry, javelins.
Mountain Tribesmen: Good defense on hills.
Armenian Cataphracts: Lighter than Sassanid but more mobile.

2. Horde Units

When a faction becomes a horde (loses its last settlement), it spawns free, high-morale units like Horde Warband and Horde Cavalry. These are not good units (think peasant stats), but they are free to maintain. The strategy is to swarm: 10 horde units versus 4 Roman units will win through sheer mass.

4. Flamethrowers (Eastern Roman Empire)

Yes, flamethrowers. The Greek Firethrower (available only to ERE in certain campaign conditions) is a siege defense unit. It spews liquid fire in a short arc. Cavalry and infantry both disintegrate. Unbelievably powerful, but incredibly fragile if flanked. Desert Raiders: Fast light infantry, javelins

Most Interesting Unit Categories

1. The Roman Factions (Western & Eastern)

Limitanei (Border Troops): Spearmen with decent defense but low morale. Perfectly average—but that’s the point. They represent Rome’s decline.
Comitatenses (Field Army): The new "legionaries." Good armor, swords, and testudo formation. Reliable but expensive.
Plumbatarii (Lead Throwers): Elite heavy infantry that throws five heavy darts before charging. Devastating vs. armor.
Foederati (Barbarian Mercenaries): Germanic spearmen or cavalry. A double-edged sword—strong but can turn on you if loyalty drops.

2. Huns (The Apocalypse on Horseback)

Hunnic Horse Archers: Faster firing rate than any other archers. Hit-and-run masters.
Noble Cavalry: Heavy lancers with excellent charge. Combine with horse archers for the classic Parthian tactic.
No infantry (almost): Their only foot unit is a cheap peasant spearman. True to history—fun and frustrating.

3. Sassanids (Persian Revival)

Clibinarii (Super-Heavy Cataphracts): Armor so thick they resist arrows. Slow but unstoppable in melee.
Elephants (Armored): Even scarier than Rome’s elephants. They tramble, cause terror, and are nearly immune to missiles.
Daylami Infantry: Heavy axemen who counter cavalry. Rare in Eastern factions—useful surprise.

4. Barbarian Factions (Goths, Vandals, Saxons, etc.)

Noble Swordsmen (e.g., Gothic Noble, Chosen Axemen): High attack, low armor. Glass cannons.
Night Raiders (Saxons): Invisible in forests. Great for ambushes.
Chosen Archers (Crossbow-style bows): Powerful but slow firing.
Berzerkers (Celtic/Germanic): Terrifying but uncontrollable once they rage—can attack your own units.

5. Nomads (Alans, Vandals horde mode)

Lancers & Horse Archers: No settlements—you literally move your "camps" as wagons. Units gain experience by migrating.
Wagon Fort (Special ability): Parked wagons act as mobile walls. Unique siege defense in open field.
