This mod lets you ingame select or deselect the IR suppressors (EVU).
Simply extract the zip in your Saved Games/DCS[version]/Liveries/Mi-24P
If you do not have the Liveries/Mi-24P folder you need to create it.
While ingame, open the refuel/rearm window and choose the EVU Off or EVU On skin, but do NOT press ok. Instead press the X on the topright of the refuel/rearm window.
You can use this with every livery you want.
