Examples

Example 1:
1 in [0, 1, 2]; // true
Example 2:
private _myArray = ["Aaa", "AAa", "AAA"]; "aaa" in _myArray; // false "AAa" in _myArray; // true // case-insensitive alternatives _myArray findIf { _x == "aaa"; } != -1; // true ({ if (_x == "aaa") exitWith { _forEachIndex }; -1 } forEach _myArray) != -1; // true, less performant but valid before findIf { if (_x == "aaa") exitWith {1} } count _myArray > 0; // true { _x == "aaa"; } count _myArray > 0; // true, worst performance // only option available in OFP
Example 3:
Arma 3:[1,2,3] in [[1,2,3], [4,5,6]]; // true
Example 4:
_isInCar = player in car;
Example 5:
_isInside = [1000,2000,0] in myLocation;
Example 6:
_isInString = "foo" in "foobar"; // true _isInString = "Foo" in "foobar"; // false
Example 7:
private _boarded = player in _groupVehicle;
Example 8:
private _onFoot = _unit in _unit; // vehicle _unit == _unit works // isNull objectParent _unit is even faster

From a description note:
<unit> in <vehicle> literally does this: vehicle <unit> == <vehicle>. If <vehicle> is the same as <unit> the expression will return true for when the <unit> is on foot and false for when <unit> is in vehicle (see example 7 & 8).
