In reply to the second question in your post... What might be done is this... all the modders that produce unit addons take a look at what the actual units in question are equipped with/wearing, and collaborate to produce the most realistic addon. There are many great addons out there already, though they must be brought up to standard and polished. You modders need to determine if you need to scrap your previous models and build new ones from scratch, ( More time consuming but better looking, IMHO. ) or simply make a few changes to the existing addons to get something out to the community quickly. Or something in between, as many existing models are fine for most of the operations these guys do, and some could be added for more spcialized roles. For instance, the USAF SPECOPS guys often would deploy with the aircrew helmet, Bibmi has PJ's equipped with this. Skaven already has great looking SEALs, but they could be equipped with the Delta caving helmet, and the aircrew helmet as well, they use all of these from time to time.
Many units in the US SPECOPS community dress and loadout with similar kit, as these forces are all a part of the US SOCOM. They maintain a certain degree of commonality in this respect so as to enable smoother operational capabiity when deployed as a joint services task force. That is, operating with other SPECOPS units.
Maybe what could be done is a generic style operator, with slight variations in kit. The uniforms would be common, ( BDU's in black, woodland, desert, and snow and/or urban, USAF style OD flightsuits, and black neoprene wetsuit, etc. ) as all these units wear them. The variations would be in helmet, ( Caving/hockey helmet's, boonie hat, balaclava, OD scarf/bandana/bandage wrap, aircrew helmet, and sometimes watchcap/ballcap. ) loadbearing gear, ( Commercially produced off-the-shelf rucksacks and vests, as well as miltay issue ALICE packs, etc. ) and weapons, ( US SOCOM forces mostly use the M-4/M203 SOPMOD these days, but some prefer foreign makes and models, while others use older tried and true weapons like the M-14, M1911 MEU .45, M-49 and Stoner machineguns.)
This is something that can only be accomplished if the modding community can put aside any ego/personalty issues, and learn to cooperate and communicate as a team. My suggestion is for all of you to get together and choose a team name/tag for the group, and a common private communcations forum. A group website could be set up as a showcase for the various addon projects, perhaps here in OFPEC. The various members vote/choose a leader, who in turn picks a second in charge. They then delegate projects to the other members who are most skilled in a particular area. This is how I would do it, and have seen done in many successful moding communities online. But the key is to work for the greater good of the game players, and resist the need for singular recognition. A kind of democratic socialism if you will.
Just my thoughts, and sorry for the long winded speech.
