This is a summary of the flag scheme I use -
Red flags get a leading '1' through '4'
Red Main & Aircraft Groups: 1
Red Helicopter Groups: 2
Red Vehicle Groups: 3
Red Ship Groups: 4
Blue flags get a leading '5' through '8'
Blue Main & Aircraft Groups: 5
Blue Helicopter Groups: 6
Blue Vehicle Groups: 7
Blue Ship Groups: 8
Group numbers are the second & third digits.
Unit numbers are the fourth digit.
The State is the fifth digit:
0: Count (use for Flag Increment and Decrement)
1: Dead, or Lost
2: Alive, or Won
4: Broadcast; enables a repeating message with Condition = Time Since Flag (Flag x), and Action = Flag On (Flag x) & Message
5: Zone Clear or Occupied Friendly
7: Zone Invaded by Enemy
8: Zone Captured by Enemy
9: Deactivated vs Dead
