This conditional count command only works if all the elements in the tested array are of the same type as the tested element.
For example, the following code will created an error, since the elements are of different types (object, number, string): _arr = [ player,100,"one"]; {_x == "one"} count _arr;

Alternatively, to avoid the error use isEqualTo instead of ==. --KK

This one, on the other hand, where all elements are strings, just like the tested element, will return the correct result of 1: _arr = ["one","two","three"]; {_x == "one"} count _arr;

Notes from before the conversion: Use this to calculate how many "M16" mags a soldier has left. {_x == "M16"} count magazines soldier1; Take care when using count to determine how many units are left alive in a group: count units group player or count units groupname Will return the number of units the leader of the group thinks are alive. If some units have been killed out of sight of other members of the group then it may take sometime for this to be the actual numbers in the group. To determine exactly how many units are really alive in a group use: {alive _x} count units group player; or {alive _x} count units groupname;
