Also roman soldiers had white tunics, not red ones. Red was used for centurions and other officiers. So i think a white tunic over mail or white mail with surcoat would be the most accurate armour possibile (but if doesn't really fit since they put the tunic under the armour, not over it :) )
Plain Board Shield, Scottish Sword, 2x Throwing Lance. Bam legionnaire kind of. Your just douched on the armour. Hopefully they will make a morion helmet with a huge plume of red feathers or maybe Final Boss will add that to the +1 +2 +3 versions of the morion helmets blah blah blah.IMO Scottish Sword doesn't really look like gladius at all, gladius is rather wide sword and plain, when Scottish Sword is kinda thin and "detailed"... Best sword for Roman Legionnare kind of character right now is Short Broad Sword IMO.
