Thanks for helping people you dont know.
Sharing knowledge is a very honorable thing to do.
Everything works as expected and I can finally go to sleep without having to google "Arma 3 Loadout scripts" :P
Best wishes and thank you again very much

Hi tried your code and still ran into the issue that no Units were spawning with the preset loadout.
I looked into the RPT file too see whats going on and found these 2 lines multiple times:

Error in expression < then { [_x] execVM "FalLoadout.sqf"};

} forEach units group _unit;

{

if (typ>
  Error position: <} forEach units group _unit;

{

if (typ>
  Error Missing {
File mpmissions\__cur_mp.lingor3\ForceLoadouts.sqf, line 8
Error in expression < then { [_x] execVM "FalLoadout.sqf"};

} forEach units group _unit;

{

if (typ>
  Error position: <} forEach units group _unit;

{

if (typ>
  Error Missing {

Thanks it works now!
But I do have another Question, when I copy and paste this code
{ if (typeof _x == "CUP_O_TK_Soldier_AR") then { [_x] execVM "RpkLoadout.sqf"; // debug systemchat format ["Replacing unit loadout: %1", _x]; }; } forEach units group _unit;
into the Loadouts.sqf to add another Unit, the Script doesnt work anymore at all.
Here is my Loadouts.sqf at it its atm (apologize my code structure):

params ["_unit"];

if (typeof  _x == "CUP_O_TK_Soldier_AA","CUP_O_TK_Soldier_AAT","CUP_O_TK_Soldier_AMG","CUP_O_TK_Soldier_HAT","CUP_O_TK_Commander",
			"CUP_O_TK_Engineer","CUP_O_TK_Medic","CUP_O_TK_Soldier","CUP_O_TK_Soldier_Backpack","CUP_O_TK_Soldier_LAT",
			"CUP_O_TK_Soldier_AT","CUP_O_TK_Soldier_FNFAL_Night","CUP_O_TK_Spotter","CUP_O_TK_Soldier_SL","CUP_O_TK_SpecOps_TL",
			"CUP_O_TK_Story_Aziz") then { [_x] execVM "FalLoadout.sqf"};

} forEach units group _unit;

{

if (typeof  _x == "CUP_I_TK_GUE_Soldier_AA","CUP_I_TK_GUE_Soldier_AR","CUP_I_TK_GUE_Demo","CUP_I_TK_GUE_Soldier",
			"CUP_I_TK_GUE_Soldier_AAT","CUP_I_TK_GUE_Soldier_AT","CUP_I_TK_GUE_Mechanic","CUP_I_TK_GUE_Soldier_TL",
			"CUP_I_TK_GUE_Commander") then { [_x] execVM "AkmLoadout.sqf"};

} forEach units group _unit;

{

if (typeof  _x == "CUP_O_TK_Crew","CUP_O_TK_Officer","CUP_O_TK_Pilot") then { [_x] execVM "ak74uLoadout.sqf"};

} forEach units group _unit;

{

if (typeof  _x == "CUP_I_TK_GUE_Soldier_GL","CUP_I_TK_GUE_Soldier_AK_47S") then { [_x] execVM "AkmGlLoadout.sqf"};

} forEach units group _unit;

{

if (typeof  _x == "CUP_O_TK_Soldier_AR") then { [_x] execVM "RpkLoadout.sqf"};

} forEach units group _unit;

I tried to define multiple classes for the "x_ == " but that messed the whole script up.
Is there a way to define mutiple soldier classes who use the same loadout without having to CnP everything with just one changed string?

@Murdock
Thank you for replying!
I did take a look at the Script Snippets and since im running multiple factions I try to use the class names of the units directly (e.g "CUP_O_TK_Soldier") rather than their role (Grenadier, Medic etc.).
Still had no luck with it.

Hello,
I have tried to run a script on my dedicated ALiVE server which forces a certain Loadout for the defined Soldiers classes (Just replacing the Gun from the Soldier).
So far it does work on Editor placed units but I had no luck with ALiVE spawned units.
Sadly I couldnt figure it out myself and with the help of the Interwebs, so I hope you guys can help me out.

I've tried using the following in description.ext based on what I found from others:

class Extended_Init_EventHandlers {
class Man {
init = "_this call (compile preprocessFileLineNumbers 'ForceLoadouts.sqf')";
};
};

ForceLoadouts.sqf:

private "_this";
_this = _this select 0;
{

if (typeof  _x == "CUP_O_TK_Soldier_AR") then { [_x] execVM "RpkLoadout.sqf"};

} forEach units group _this;

RpkLoadout.sqf:

//Rpk Loadout

waitUntil {!isNull player};
_unit = _this select 0;

removeAllWeapons _unit;
_unit addMagazines ["hlc_45Rnd_545x39_t_rpk", 4];
_unit addWeapon "Weapon_hlc_rifle_rpk74n";

if(true) exitWith{};

Any help is greatly appreciated!
