Missing units/Imposible to train. Latest SS, with RR

[ColdFire]

I am playing the latest SS with RR, and when I look and buildings in the building browser, I cannot find how to train many of the unit avalible in custom battles. Are they unlocked as time passes, or are they simply not listed? I have noticed this most when playing Late era, if that is relevant.

Thanks in advance,

It's my understanding that, with Real Recruitment, the increasing "levels" of unit types are unlocked at certain dates. This is, sensibly, to prevent someone from running around in 1150 with top-tier units.

The dates themselves are around here somewhere, but I don't think the first "unlock" is until the mid-13th century.

Cheers.

Taken from RR thread. Note that a new Beta is now up and running, most likely with different dates then these.

Heavy Mail: available whenever an Armourer is built. This will typically be late in the Early Era and is approximately the correct timeframe.
Partial Plate/Mail: Early-Mid High Era, about 1275
Full Plate: Late Era, about 1380
Gothic Plate: Mid Late Era, about 1450
Handgun: about 1310
Arquebus: about 1466, Spanish Arquebus about 1444
Musket: about 1502
Pikes, Polearms, Heavy Crossbows: about 1310

Hmm, I never knew that...
