In SOG:PF we use submunition to prevent smoke grenades from bouncing, this seems to duplicate the deployed shotSmokeX submunition by player count:
- Spawn Grenadier unit
- Add vn_40mm_m715_smoke_g_mag
- Shot the smoke, it uses vn_40mm_m715_smoke_g_ammo
- count allMissionObjects "vn_40mm_m715_smoke_g_sub_ammo" return the amount of the connected clients
