Looking at leaked game sources I can see that this behavior is entirely hardcoded and simply spawning BLUFOR or OPFOR laser target when you lase as INDEP side is not a proper solution.
Proper solution:
- Introduce new special sides into the game: TWestEnemy, TEastEnemy, TGuerrilaEnemy, TCivilianEnemy which will be enemy only to West, East, Guerilla and Civilian sides accordingly (as well as to TEnemy of course)
- Create laser target objects for each of these new virtual sides
- Create laser targets with enemy side depending on side of unit that does the lasing
