Absolutely love the potential I see here. I have always liked the idea of a Scandinavian military.
I do have some critiques I would like to make;
I understand you guys would like some diversity in the arsenal of small arms (M16s are in every other game) but the Negev for a light machine gun? The Negev is Israeli and the CSAT units are using a copy of it http://www.imfdb.org/wiki/ArmA_III#IMI_Negev nothing major but just something that was scratching my brain. If you guys are open to some opinions, I would suggest http://world.guns.ru/machine/usa/lwmmg-e.html and again, I would steer clear of weapons like the M249s and 240Bs as they see too much light. Up to you, but the LMG I linked has a similar vibe to the firearms you have already chosen and I think it would look slick and unique.
Another thing that got my attention was the camouflage patterns. The camouflage pattern really contributes to making the identity of any military. The camos you had listed reminded me a bit too much of the AAF camo with the darker greens and digital pattern. I understand you are a bit unsure of what design you wish to go with but I have a design that you might like. http://www.srvv.org/en/surpat/ The colour scheme would work well with with the arid environments of Altis and the lighter colours would go with Scandinavian forests in winter and in summer.
It's completely up to do with your mod.
I just felt like sharing some feelings as I would love to see this mod go far.
Keep up the good work! and I can't wait for some more updates! :)
