I recently went back to looking at WinterFor after couple of games running NCA. Under ORC Troops it reads: Special Fireteam: Core. Up to 2 Orc Troops can be a part of a Fireteam: Core of this Sectorial Army. So can ORCs join a Core of Nisses? There is a Special Fireteam mention under Fusiliers allowing up to 2 ORCs to join them, but there's no such Special Fireteam option under Nisses, only for a Machinist to join. Coming from Varuna and NCA I assumed that SvalORCs work similar to those sectorials (up to two in Fusiliers Core). I'm stuck using the mobile app because my phone refuses to open Army's web version to check if they are written the same way.
