(ArmA3 1.16) for multiple comparisons, we can use the example below for more accurate compare than BIS_fnc_arrayCompare or BIS_fnc_areEqual: fnc_areEqual = { private ["_b","_var1","_var2"]; _b = true; for [{_i = 1},{_i < (count _this) && _b},{_i = _i + 1}] do { _var1 = _this select (_i-1); _var2 = _this select _i; if (!(_var1 isEqualTo _var2)) then {_b = false;}; }; _b }; ["A","a","a"] call fnc_areEqual; // false ["A","a","a"] call BIS_fnc_areEqual; // true

The behavior of "var1 isEqualTo var2" is pretty much equivalent to "var1 in [var2]", plus the ability to compare arrays, and slightly better performance.

To clarify AgentRevolution's note, he is saying that the in command and isEqualTo use the same comparison algorithm. If we were able to look at the code for the in command, I bet you would find isEqualTo in there also.
