AGGRESSIVE COMBINED ARMS FORWARD CAMPS VELITES + LEGIONARIES FOR THE HUMAN META
PHASE 00 Doctrine // The Three Laws READ ONCE
LAW 01 — BRING THE BASE TO THEM
The Military Camp is your civ's signature. *Don't fight from home — fight from a forward camp.* Production where the action is.
LAW 02 — PRESSURE BEATS COMPOUNDING
You can't out-boom Medium AI. *Don't try.* Disrupt their eco at minute 7-10 with cav harass and forward towers. Slow their snowball below your line.
LAW 03 — COMBINED ARMS, NEVER PURE
Hastati + Velites + Equites together. Never spam one. *Romans win by stacking advantages*, not by maxing a single unit.

PHASE 01 Foundation // Boom + Scout 00:00 — 06:00

Objective

Modest boom. *Don't try to match Medium's eco.* Just get to 25 villagers and Phase II with enough resources to start aggressive plays at minute 7.

// Roman-Specific Pitfall

Don't fall in love with Roman Legionaries yet — they're Phase III via Marian Reforms. In Phase I-II you fight with citizen Hastati. They're decent but not elite. *Pressure the enemy, don't try to win head-on yet.*

PHASE 02 Forward Camp // The Roman Signature 06:00 — 12:00

Objective

Establish forward presence with a *Military Camp*. This is THE Roman play — production at the front line. Disrupt their eco before it snowballs.

Outposts
×2
Both flanks covered. AI scouts walls — uncovered flanks become highways.
Military Camp
×1
Halfway between you and them. Trains Roman line troops. Forward production line.
Harass Squad
3-5
Equites cycling on their workers every 90s. Kill 6-8 villagers per loop.

The Military Camp build sequence

  1. At minute 8, send 1 villager + 3-4 Hastati to a midpoint between bases
  2. Drop Military Camp under cover of your escort troops
  3. The escorts garrison the camp briefly while it builds (~45s)
  4. Once up, queue 5 Hastati + 3 Velites on loop
  5. Camp is now a *forward fortress AND barracks*. Reinforcements spawn 10s from the fight, not 60.
WHY THIS WINS
The Military Camp is *built* for the human meta. It's a forward base that comes with production. You don't need a second CC + barracks far from home — *one building is both*. Romans cheat the forward-base play.
PHASE 03 Pressure // Active Disruption 12:00 — 20:00

Army composition // 40 units

Romans are *combined arms*. No single unit dominates — the mix is the strength.

  • 30% Hastati/Principes — front line, ~12 units
  • 30% Velites — ranged DPS, ~12 units. *Your match against Roman skirmishers if facing one yourself; also great vs pikes.*
  • 20% Equites — flank + raid + siege killer, ~8 units
  • 15% Slingers — anti-pike, anti-building, ~6 units
  • 5% Scorpio — 2 bolt shooters for wall cracking

The Disruption Loop

EVERY 90s
→ 4 Equites to enemy woodline
KILL 6-8
→ workers, retreat
SLOW THEIR ECO
→ delay their snowball
YOU OUT-TEMPO
→ not out-boom

The Marian Reforms moment

When Phase III hits, *research Marian Reforms* immediately. This converts your citizen-soldiers (Hastati/Principes/Velites) into *Legionaries* — heavily armored elite infantry that crush almost anything in melee.

This is the Roman win condition: *get to Marian Reforms, convert your existing army into Legionaries in one click, and push.* Your minute-20 army instantly becomes ~30% stronger.

Order of operations

  1. March *whole army* to ONE target — usually their secondary base or military camp
  2. Scorpio softens walls/towers from range while Legionaries hold the line
  3. Equites flank around to kill their ranged units and any siege they bring
  4. Velites kite their pikes if any
  5. Kill the buildings, retreat
  6. Wait 3 min, repeat at their main base
ROM.01 Military Camp // Civ Signature CORE FEATURE

What it actually does

  • *Trains all standard Roman units anywhere on the map* (Hastati, Velites, Equites, Principes)
  • *Garrisons units for healing + arrow fire* — like a fort, but cheaper
  • *Buildable forward* — the explicit purpose
  • *Counts as territory* — extends your influence outward

When to build

  • Camp #1: Minute 8-10, halfway to the enemy
  • Camp #2: Minute 14-16, on the other side of the map (denial / second front)
  • Camp #3+: As you push deep, drop camps as you go

The 'fortified advance' play

March a small army forward. When you reach a new piece of ground, drop a Military Camp. Reinforcements from the camp spawn at the new front. You repeat — march, drop, reinforce, march. *You're slowly walking your base toward theirs.*

SIGNATURE PRINCIPLE
The Roman Empire didn't expand by long marches. *It expanded by walking forward and building castra (forts) wherever it stopped.* The Military Camp is the same idea, gameplay version. Use it that way.

PRIORITY
Marian Reforms is your most important Phase III research. It transforms your existing army for free. Don't queue champions before researching this.
ROM.03 Heroes // The Aura PHASE III · ONE OF EACH

Roman heroes are trained from the *Fortress*. One of each at a time. The aura buffs nearby units in a ~30 tile radius. *Keep them alive.*

HeroBuffsPick when
🦅 Scipio AfricanusInfantry attack / armor — your line gets strongerStandard combined-arms push
⚔️ Gaius MariusMarian Reforms accelerator; Legionary bonusGoing hard on Marian Reforms strategy
🛡️ Fabius MaximusDefensive buffs; armor + repair speedYou're behind and need to stall + rebuild

Aura radius varies by patch. Position the hero in the *center* of your formation — not the front (he dies), not the rear (aura doesn't reach).

// Common Mistake

Sending the hero alone to scout. He dies to 3 spearmen. Aura gone, ~15-20% army strength gone instantly. *Always escort.*

No Velites in armyVelites are top-tier — high mobility, dual mode. Always include.
