you could use more models in that list
imho. The guard's strength in 500 pt games is the ability to field a gak ton of troops with decent and cheap heavy weapons, which is lost if you take too many upgrade options. Currently you have 0 models, which will result in losing every game, I'd try to get at least 50 in the list. Also you need 1
hq and 2 troop choices to be a legal list
