Oh its can be everything.
First of all you should try to run the mission on any other PC to have a clue if that is not hardware problem.
Try to change malloc option to

-malloc=tbb4malloc_bi

This would be not so easy using that script, because you need a script which will detect if there any entities near. Otherwise it will remove objects which are currently used by enemy .This will ruin the mission as well.

Script organize arsenal gear to defined mode
WEB

Hi reduce the enemy activity and the roadblock count

Here are video which is showing differences between roadblocks types.
First 5 are default ALiVE roadblocks.

All for more fun. There also full truck of nasty insurgents driving around. Imagine that: You drive doing a regular patrol then suddenly a truck appear from the other side, stops and bunch (15) of insurgents is jumping out. :-)

All is defined by mod author. If he has planed to create a faction with vehicle group, than you have such groups in faction.
You can find all in editor entities selecting proper faction and groups when desired mods are loaded.
MY config patch for OPF_MTI_F is based on CSAT, uses massi takistan units HD with
Infantry, Support Infantry and Motorized Infantry

Well i can show you how.

First you need to define extened init eventhandler inside description.ext.

class Extended_Init_EventHandlers	{
	 
class B_CargoNet_01_ammo_F	// classname of the box
 { 
		
     init = "(_this select 0) call (compile preprocessFileLineNumbers 'scripts\arsenalCrate.sqf')";
     
 };
};

scripts\arsenalCrate.sqf

private "_crate";

_crate = _this;

[-2, {
_crate = _this;
_crate allowDamage false;
["AmmoboxInit",[_crate,true]] spawn BIS_fnc_arsenal;
}, _crate] call CBA_fnc_globalExecute;

You need to adjust stuff because above example is written for usage of ACE mod.

Sure. You need to use Extended init eventhandler

You need to create event script where in most needed moment you call those task creators.
