I'm sure it means the compass direction. The thing is, "enemy forces" tells you nothing about the composition of those forces. And also, I never memorize the compass directions on any given map...I think it's just much easier to say "bar side" or "ref side" or "left/right" with the assumption that "front" is pointing towards enemy base.
Triple post, woop.
Made a video for the Advanced Naval Yard, in-game. Keep in mind this is still somewhat a work in progress (note the lack of small crates and such), but the overal design is final.
Please ignore the water in this video, it's fooked, pending overhaul.
