Description from original post (created 2012-05-26 03:54):
hese guards patrol Haafingar Hold and Solitude.
They wear a red cloth version of the guard armor. The armor is a scaled vest with a chainmail shirt underneath. In addition, as Solitude is the Capital of Skyrim and under Imperial Legion control, the guard also wear Imperial Bracers and Imperial Boots.
The guards also carry a round, red, wooden shield with a painted motif of a wolf.
The guards around Castle Dour are Imperial soldiers and will wear full Imperial Armor, though they are still named Solitude Guard.
During the course of the civil war, the Stormcloaks may occupy Solitude and replace these guards.
