Posting this for my own purposes, I used Droke's former release of the infantry version but I fixed the frames (he started his anims at the wrong starting facing) so it would function properly. I don't require any credit, but Droke does so just credit him.

For the projectile, you can use the existing DRONP since this is the base terror drone graphic. If you change the infantry version, your changes should reflect in the projectile version as well to prevent a graphical distortion when the Drone jumps.
