add Insignia to AI

[Casio91Fin 31]

How could I make this work?

_AI_Leader = New_AI_Group createUnit [JalkavakiJohtajat select floor (random count JalkavakiJohtajat), _AI_Spawn_Pos, [], 0, "NONE"];
if (_AI_Leader == "I_officer_F") then {_AI_Leader setRank "LIEUTENANT"; [_AI_Leader, "LIEUTENANT"] call BIS_fnc_setUnitInsignia;};

else they are.
_AI_Leader setRank "SERGEANT"; 
[_AI_Leader, "SERGEANT"] call BIS_fnc_setUnitInsignia;

_AI_Leader is an object (unit), "I_officer_F" is a class of unit. You can't compare them by equal term.

if (_AI_Leader isKindOf "I_Officer_F") then ....

"LIEUTENANT" or "SERGEANT" are not insignia but rank.

i figured out what was the problem
if (typeOf _AI_Leader == "I_officer_F") then {_AI_Leader setRank "LIEUTENANT"; [_AI_Leader, "LIEUTENANT"] call BIS_fnc_setUnitInsignia;} else {_AI_Leader setRank "SERGEANT"; [_AI_Leader, "SERGEANT"] call BIS_fnc_setUnitInsignia;};
