Code Changed KFVetCommando.uc to mutator (how?)

[DoDS]

I have changed KFVetCommando.uc:

static function AddDefaultInventory(KFPlayerReplicationInfo KFPRI, Pawn P)
{
	if ( KFPRI.ClientVeteranSkillLevel == 5 )
	{
		KFHumanPawn(P).CreateInventoryVeterancy("KFMod.AK47AssaultRifle", GetCostScaling(KFPRI, class'AK47Pickup'));
	}

	if ( KFPRI.ClientVeteranSkillLevel == 6 )
	{
		KFHumanPawn(P).CreateInventoryVeterancy("KFMod.AK47AssaultRifle", GetCostScaling(KFPRI, class'AK47Pickup'));
		KFHumanPawn(P).CreateInventoryVeterancy("KFMod.Bullpup", GetCostScaling(KFPRI, class'BullpupPickup'));
	}
}

how make mutator for apply this changes to game?
