Switching out units VIA Story Scripting. Thread - Yuuzhan Vong at War mod for Star Wars: Empire at War: Forces of Corruption

I was making multiple variations of Red Squadron and was wondering if it was possible to have them automatically switch variants when one dies via story scripting. I was planning on going Red Squadron (Scarif) --> Red Squadron (Yavin) --> Rogue Squadron. I have enabled Hero Perma-Death so I wouldn't think I would need to remove the dead variations with the script. Here's what I've got so far, I have no idea if it'll work. I used Thrawn's Revenge's tech switching code as a base. Any help would be appreciated.

        <Event Name="Red_Squadron_Switch_1">
  		<Event_Type>STORY_TACTICAL_DESTROY</Event_Type>
  		<Event_Param1>Red_Squadron_Scarif_Space</Event_Param1>
		<Event_Param2>Empire, Pirates, Underworld, Hutts</Event_Param2>
 		<Reward_Type>SPAWN_HERO</Reward_Type>
  		<Reward_Param1>Rebel</Reward_Param1>
		<Reward_Param2>Red_Squadron_Space</Reward_Param2>
		<Reward_Param3>Yavin</Reward_Param3>
	</Event>

	<Event Name="Red_Squadron_Switch_2">
  		<Event_Type>STORY_TACTICAL_DESTROY</Event_Type>
  		<Event_Param1>Red_Squadron_Space</Event_Param1>
		<Event_Param2>Empire, Pirates, Underworld, Hutts</Event_Param2>
 		<Reward_Type>SPAWN_HERO</Reward_Type>
  		<Reward_Param1>Rebel</Reward_Param1>
		<Reward_Param2>Rogue_Squadron_Space</Reward_Param2>
		<Reward_Param3>Hoth</Reward_Param3>
	</Event>

I saw a tutorial for this just the other day but can't find it again. You're looking in the right place. If I find the one I was looking at before I'll let you know since it covered changing out an x-wing squadron for a more advanced model which would be perfect for you but here's a longer one that should help:

Moddb.com

Assuming that your units are coded as heroes you might find this tag more effective

STORY_DEFEAT_HERO

(Hero name)

Triggers when the specified hero is defeated in combat.

The other tag you might want to consider is this tag

STORY_DESTROY

(Object name)

(System name)

(number to destroy)

(who does the destroying)

(filter)

Triggers when a specified object or objects are destroyed in galactic mode. If you want to trigger via destruction in a tactical combat, use STORY_ TACTICAL_DESTROY instead.

I believe that the STORY_TACTICAL_DESTROY only works during a battle. So a death during GC would not be counted
