Command: Modern Operations has reached an outstanding milestone. The Open Beta for Build 1121.4 has introduced a major new feature: the Fog of War (FOW) for Tacview 3D view.
When God's Eye view is disabled, the Tacview window will now display only own- and friendly-side units plus any detected contacts. Displayed contact shapes start from generic semi-opaque placeholders and then switch to more specific (and solid) shapes when/if they are sufficiently classified/identified. If God's Eye is active, all units are shown as before.
(Known current issue: Switching side or toggling God's Eye status forces the Tacview window to close and re-open).
Important note for Steam users. You can apply this update manually on top of your Steam installation. This new beta will soon also be available on the Steam beta branch, and after it checks out also on the normal distribution branch.
