But for real, maybe a minelayer unit? It's supposed to be something new, has been asked for in the past, and "brand new units possessing a unique feature to CoN, which will further contribute to the micro aspect of warfare." sounds like the addition of a new element to the battlefield. Possibly mines, but I'm just guessing as that seems to meet the criteria in Yak's post, and it may be what that vague picture is featuring.
Also this is a question for forum moderators and probably offtopic but still I want to ask you: "Is there any chance that units like MLRS, SAMs or destroyers will have their 2nd and 3rd model changened for thier IRL system. This game has nice 3 stage models of military vehicles but it's annoying to have BM-21 Grad model for BM-30 system or Darling class destroyer model for early cold war European destroyer." If there is any thread where I can discuss it or any clear answer I would appreciate if any of you mods can tell me
