Oh right, good point on the six different scripts. Every time I post something like this I have to think about it first, because I've only been playing a mod for over a year now. I have to try not to post things that don't apply to the standard campaigns, and this is one of those times that I failed. So I should remove my comment as being not applicable, but instead I will stick my neck out further
In 653H/N all of those six DE's were removed and replaced with one that uses those triggers in Post #2. My reasoning was that historically Mussolini turned down Hitler's offer of assistance in Afrika, but then requested assistance once the UK had its' great success in routing the Italians. Therefore, the DE for DAK only occurs if those conditions are met. Similarly, the UK gets its' DE to reinforce Egypt only if there are German units in Libya via:
; German units in Libya
#CONDITION_POSITION= 191,124 [5,5] [2,2]  
The idea is that both DE's may not ever fire, depending on the conditions. The DE's are more of a back up if the player needs them, and are a safety net for the Computer Player. It's a different situation from the stock campaigns.
