i've seen plenty of pics from 2009 etc and even into 2010 with men wearing IBAs. there is only 1 unit with the iba at the moment.. and I am going to switch over to my new IBA model (has a more distinct shape than the flat one i use currently)
as for the mc men, i'm considering just doing them in UCP rather than MC as nixo made a very nice set of mc men.. although they wear all crye gear. maybe in the future. model adjustments will be made so it's just a 'flat' ACU under it.
for the helmet, currently i am reworking textures and also trying to make it more thick. some pics would be good too
