I talked with the artist who created the faction art, and he said it was okay to borrow it.

Here are icons for power armor, not quire satisfied with power armor 4 icon but maybe I will be able to work on a better version when I find out better ways to make icons. Also I have borrowed a sprite for reaserch of belt immunity equipment, but i don't know if I am allowed to use it. If it's okay ...

I have made some sprites to the reaserch of power armor MK 3 and 4, if this is useful i can make sprites for icons too.
