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 the introduction of the findIf command { if (_x == "aaa") exitWith { 1 } } count _myArray > 0; // true { _x == "aaa"; } count _myArray > 0; // true, worst performance, only option available in OFP

Example 3:

[1,2,3] in [[1,2,3], [4,5,6]]; // true - Arma 3 only

Example 4:

private _isInCar = player in Car;

Example 5:

private _isInside = [1000,2000,0] in MyLocation;

Example 6:

private _isInString = "foo" in "foobar"; // true _isInString = "Foo" in "foobar"; // false

Example 7:

private _onFoot = _unit in _unit;

Other options:

private _onFoot = vehicle _unit == _unit;

private _onFoot = isNull objectParent _unit;

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).
