I was also convinced that the engines were turbomeca Bastan.
But in wikipedia says that the military version was equipped with the Astazou ... just like the pucará.
That's why I asked the question.
It seems that Dassault put the Bastan to the civilian model, calling it MD.415 Communauté and in the only military model called MD.410 Spirale, put the Astazou XIVD.
I can not find the reason of putting a 360kw less powerful engine into the military model ... Will it be by autonomy?
I guess you posted the only military version MD.410 Spirale
