I’ve pulled out some of the Tau fleet models (Kor’vattra list), to see if they match with some proxy Custodian/Castellan/Warden (Kor’or’vesh list) models I bought from ShapeWays.com.
I have 2 Messenger Class Escorts, which in games would act as a support for other vessels. This units special rules make it a buff unit only. They have minimal battery firepower.
With torpedoes and high firepower batteries, the Defenders Class are the workhorse escorts from the Kor’vattra list.
More on the proxy Kor’or’vesh models later.
