I was part of the conversion package sent to Europe in 1973 to convert the Sergeant and Honest John units to Lance, after training at Ft. Sill and WSMR from late 72 to Spring 73. We had a team of 23 officers and NCOs that came to Europe in April of 73. We converted the 5/77 at Camp Pieri from Sergeant to Lance and the unit was redesignated as the 1/333 during the summer of 73. We got the unit certified in Sept 73. After that, we assisted with the conversion of the other 5 units in FRG. 2/42 at Giessen was the second unit converted, then the 3/79. I have forgotten the order the remaining units were converted (it's only been >30 years!).
I looked on Google Maps recently and Camp Pieri is now a subdivision (here are the coordinates in case you have forgotten: 50 deg, 03' 54.87" N and 8 deg 11' 11.13" E).
LTC Holland was the Bn commander and Maj Price was the XO. HHQ Btry CO was Cpt Gary Wade, A Btry CO was Cpt Shel Alsup, (Cant remember B, and C Btry.) Svc Btry Co was Cpt Glen Dunham. CPT Ross Porter was S-3. I served as A Btry 1st Plt Leader, B Btry FDO and Bn FDO. Was there until Dec 1976. Other folks I remember SFC Tommy Isham, SFC Gene Lewis, Sgt "Soupy" Sales, Moose (the civilian who ran the mess hall).
Other platoon leaders were Dave Vance, Chet Wingate, Steve Plott, Joe Adams, Al Barlow, Rick Smith, Phil Taylor, Dwight Danielson, and Terry Johnson. Marty Abeyta was our civilian Tech Rep.
