Your most commonly trained unit

[Abokasee]

In each of your TW games, what was your most common unit, not your faviourite but your most common

STW: No-Dachi Samurai

MTW: Feudal/Chivarlic men~at~arms

RTW: Hastati

MTW2: Spear Militia

[macsen rufus]

Hmmm ...

STW: Yari samurai
MTW: the best spear unit available at the time, depending on faction
RTW: n/a
MTW2: n/a

[The Wandering Scholar]

I spam hastati with the Romans

[Eyes330]

RTW: Early Legionary Cohort or Phalanx Pikemen

EB: Milnaht (Belgae Swordsmen) or Akontistai/Toxotai (Hellenic Skirmishers/Archers)

M2TW: Billmen or Kazaks

[Zim]

Hmmm...

MTW:VI Either plain old Vikings, or Gallowglasses.

RTW: Probably Hastati, but only because I tendd to finish the game before having much time to play around with legionaries.

EB: Classical hoplites, largely because even when I wasnt playing the KH I'd still hire them as mercs all the time. A possible contender would be those early swordsmen the celtic factions get, the fellows with the longsword who actually wear shirts (can't rmember the name. ).

MTW2: Hard to say, probably either Italian Militia or dismounted Dvor (the former as a bread and butter unit, and the latter as one of my all around favorite units and main component of my Russian armies).

Broken Crescent: So far, Sudanese Longbowmen, or maybe Saracen militia (crappy but cheap and plentiful). This will likely change as I try more factions.

[Ramses II CP]

The best available spearmen. Everything else would change depending on the era, types of cavalry, types of ranged weapons, but I always bring the top tier spearmen with my armies in quantity... and not pikes, halberds, etc.

Even in Broken Crescent where I'm playing a faction without good spearmen, my offensive and defensive armies always have a substantial collection of spearmen.

In my Lusotana and Makedonia EB campaigns: Akontistai. Best for garrison duty.

[TruePraetorian]

hastati or legionary cohort

Armored Hoplites in Rome
Comitatenses in BI

I don't play Shogun or Medieval often enough to have a common unit.

[Ignoramus]

MTW: Urban Militia
RTW: Round Shield Cavalry
MTWII: Spear Militia

I agree with most other posters - it tends to be spearmen. (The only exception is as Rome.) I am not sure if this is because they are good, or instead because they are the worst unit and so die a lot, needing to be replaced. They are cheap, low tech and can hold off the enemy long enough for the real battle winners to do their job.

My killer units tend to be archers and heavy cavalry, but they tend not to die and I keep their numbers down for realism and to maintain the challenge. The poor spearmen form the frontline and so get hammered by everything - archers, cav, swords and enemy spears. Swords tend to be better, but are harder to get and more survivable.

STW: Yari samurai
MTW: Chivalric sergeants (or feudal sergeants on early)
RTW: Hastati or principes
BI: Plumbatarii (so much better than comitatenses)
EB: Hastati or principes
M2TW: Armored sergeants (so much better than spear militia, but still lousy) - mercs if England

[A Norseman]

Hmm.. tricky

MTW: Vikings.
VI: Viking landsmenn
RTW: Hasati or legionaries.
BI: Comitatenses
MTW2: Dismounted feudal knights or Longbowmen.

[Punicus]

RTW: Long Shield Cavalry (Carthage) and Hoplites (Greece)

[Eikon the Magistrate]

MTW - Spearmen!
MTW2 - Spearmen!

[The Wandering Scholar]

RTW (Macedon) Pikemen with very long spears!
