Using the Dogfight Module for ACM training allows for many, quick repetitions in a repeating setup.

Server Setup

Moderator starts IVC Server and BMS Server (BMS Server doesn't need to be in 3D)
Players join Server lobby
We divide the players into reasonable flights with good distribution of experience
Each flight gets a callsign assigned: Claw1, Mongo1, Bull1, Nimrod1, Blazer1
Each flight is "hosted on the server" by a "Flight Host" (preferably Roster)
IVC check with everybody in the lobby
Briefing

Game Setup

The "Flight Host" starts a game online, and sets everything up:
Dogfight - Match Play
Uncheck "Unlimited Guns" and "ECM"
BVR Tactic: "Random"
Range: 50 NM (more distance is better to set everything up)
Altitude: 20000 FT
Points: 20 (we'll end the game after a set time)
Radar Missiles: 0
All-aspect IR Missiles: 0
Rear-aspect IR Missiles: 2
On the Red Team, create flights until you get your callsign, make sure it's F-16s
Join the flight with the assigned callsign, and delete the other flights
On the Orange Team, create a Bandit flight with 2x MiG-21 Veteran
Choose a nice spot over the water on the map

Edit or add the following lines to your "callsign.ini"

[COMMS]
Comm1=14
Comm1_Comment=(open)
Comm2=15
Comm2_Comment=(open)

Once everything is set up, the Flight Host calls the other players one by one to join the game
First #2, he joins the Flight Host's game on the server, and then the Flight Host's flight on the Red Team
When #2 is finished, Flight Host calls in #3, finally #4

Flight Host calls his flight to Commit, everybody clicks "Takeoff"
First session might be chaotic due to delayed joins
Flight Host makes sure his ACMI is recording
Flight Host should make notes after each round to make it easier to find highlights for Debriefing
In the pit set VHF channel 15 for flight comms, and UHF channel 14 for IDM (and trans-instance interflight comms), TACAN as desired

After 30 to 40 minutes of play time, Moderator calls end of the training on UHF14, all flights finish the current session, and join Debriefing channel.
Short high level debriefs by flight
ACMI debriefing by flight, capped to 10 to 15 Minutes by flight, depending on player count (Moderator takes time)
