are military wings / grill panel / bonnet same as normal S2.

I believe so with the exception of the wing fronts, military ones are vertical, civilian side by side.

And the military grille itself sometimes doesnt have the cut out for the bonnet latch.

All of the panels will fit with no issues. The wing front, as said above, might have the lights vertical rather than horizontal - makes no difference at all though!

Some of the military wings also had a hole half way along the side panel which was fitted with a rubber buffer to stop the doors hittting the wings if the stops were removed!
