HT9A8 'Istrenyr' Main Battle Tank

A tank from the 5th Brigade the Guards Grenadiers of Horse, who operate a little further north of the capital area in Anemos Major in the Duchy of Fierei where the land is a lot more level with far fewer trees than the forested regions that lay to the south.

This is a First Production Standard vehicle - essentially, Block I.
