which ever artillery makes the loud whistling sound before landing and creating a massively loud explosion that lifts dirt and debris 100s of feet in the air and drops my frames by like 10. There's about 10 of them and they do so much damage so quick and in such a close area it's hard to escape it once it drops.
on map, stuka zu fuss, or walking stuka, 100fuel unit from OKW's mechreg.
a note about sector arty for okw as well, it only seems to strike near the actual cap point it self, not roaming throughout the territory like CTP, so i find it easy to dodge.
