For example because featured FAF version is incomplete Shep? It has only Unleashed + Global Icon Support + Alternate Reality (only in vault - which don't work anyway because it requires a little change in files I was nice enough to post as a separate topic).
As for the question and actual help to the person in need:
a) Use this links to download all the elements of BlackOps:
http://forums.gaspowered.com/viewtopic.php?t=31172b) Unpack them to Your ...blah_blah_something_dependant_on_your_system.../MyGames/Gas Powered Games/Supreme Commander Forged Alliance/Mods
c) Be quite sure that there is only 1 folder between Mods and actual Mod files so it is like Mods/BlackOps/HERE ALL THE DATA instead of Mods/Mods/BlackOps or Mods/BlackOps/BlackOps
d) Launch the game (via Forged Alliance.exe in Your installation directory OR via Forged Alliance.exe in c:/ProgramData/FAForever/Bin if You want newest patch). Strongly suggested FAF patched launching.
e) Go to Your Extras -> Mod Manager in game and tick everything that has BlackOps name in it.
f) Voila - Done. Should work 100% fine.
P.S. If You want Alternate Reality as well (which is strongly unbalanced - just 4 units that wasn't finished yet realesed as a separate sub-mod) You must use the fix I posted here:
