February 18, 1968, I was the Arty FO assigned to Fox 2/26 Marines on Hill558. Hill 950 was under attack and had taken numerous wounded. I used my training and located the offending weapon that was shelling the medvac choppers. Calling in arty was out of the question sowed around the hill looking for someway to take out this weapon. I stumbled on a 106 on a mule, as I was the only one that could see the firing pit, I was given the seat. Three 50cal spotters and one HE round the 82 was seen flying through the air. What a weapon, nothing else on Hill 558 could touch it.
