Adding mission eventhandlers fails with foreach

[alleycat 28]

Attempted to draw icons for every player on the server:

	{
	addMissionEventHandler ["Draw3D", { drawIcon3D 
										[
											"\A3\ui_f\data\map\markers\military\dot_CA.paa",
											[1.0,1.0,1.0,0.4],
											[(getPosATL  _x select 0) ,(getPosATL  _x select 1), (getPosATL  _x select 2) +0],
											1.0, 1.0, 360,
											format["%1 %2m", name _x, floor (_x distance player)],
											0,
											0.03,
											"puristaMedium"
										]; }];


} foreach Allunits;

throws many errors. However using that setup on a single unit without the foreach does work. Am I not seeing the mistake or is it not possible to add drawicon handlers to anarray of things?
