Small oversight, SPG-9 vehicle magazines use Metis/Vorona pictures.
"SPG9_HEAT"
getText(configFile >> "CfgMagazines" >> "SPG9_HEAT" >> "picture") => "\a3\Weapons_F_Tank\Launchers\Vorona\Data\UI\icon_rocket_vorona_HEAT_F_ca.paa"
"SPG9_HE"
getText(configFile >> "CfgMagazines" >> "SPG9_HE" >> "picture") => "\a3\Weapons_F_Tank\Launchers\Vorona\Data\UI\icon_rocket_vorona_HE_F_ca.paa"
Can be seen using this code bit:
private _compose = [ "SPG9_HEAT" ,"SPG9_HE" ] apply { image getText(configFile >> "CfgMagazines" >> _x >> "picture") setAttributes ["size", "10", "shadow", "0"] }; {if(_forEachIndex > 0) then {_compose insert [_forEachIndex, [" ", lineBreak]]}} forEachReversed _compose; hintSilent composeText _compose;
