How to make boundry for whole team?

[SteelSampson 1]

in the On ACT slot write OPFOR1 setdamage 1; "OPFOR1" being whatever name you assign to the unit.

How do I make this work for the whole OPFOR team tho?

[squeeze 22]

{if(opfor == side _x) then {_x setDamage 1}}forEach allUnits;

This didn't do anything... thanks for the help tho.

Do you mean for the whole side instead of the whole team?

try in the leader's init (on Act) field just for the team/group:

{_x setDamage 1} forEach units group this;
