I've come up against a requirement to Spycraftise the trooper armour (specifically, the personal armour since that triumphed over plans for an armoured bobcat assault) from XCOM: UFO Defense.http://ufopaedia.org/index.php?title=Armour
for the base, unconverted stats.
What would the basic armour best map to in SC2 terms?
It depends what your weapons look like. Off the top of my head I'd say something like Modular Tac Armor, Vest and Guards with Trauma Plates and Nomex Underwear, or Riot Armor with NomexUnderwear. I'd use either Plate Armor (from The Shop) or Iron Warrior Power Armor (from The Pan-Asian Collective) for power and flight suits. They're both SEH (SC1), but converting them isn't that difficult.
