Military History/L-4 Liaison Planes


Dear Mr. Vargas,

I'm wondering if you can help me identify the Army Air Force unit that supported my father's field artillery battalion with two liaison planes. It is my understanding that the liaison planes and their pilots were not members of the Army outfit they supported, but rather, members of the Army Air Force attached to that unit. The spotters who flew with the pilots were, however, members of the supported unit, correct?

I believe the planes were Piper L-4s (see attached photo). I do not know it for a fact, but I believe the plane in the photo is most likely one of the two. Can please please confirm the airplane model from the photo?

The unit supported was the 243rd Field Artillery Battalion (8 inch gun), ETO, US 3rd Army. The pilots were Lieutenants Charles H. Brockmeyer and Vernon W. Lamoureaux.

Your help is greatly appreciated,

Hello Mike,

Yes, the Liaison Plane in the photos is an L-4 Grasshopper, the militarized version of the J-3 Piper Cub.

Here is more information on the J-3 Piper Cub / L-4 Grasshopper.

Lieutenant Charles (Chas) H. Brockmeyer, was an Artillery Officer who supplied the photos of the "Battle Diary: The Story Of The 243rd Field Artillery Battalion In Combat (1946)"- By Frank Smith Illustrated, Photo By Chas H Brockmeyer

Most units that had Liaison Planes, especially the for Artillery…the Liaison planes were assigned to the units just like jeeps were and treated as such.

The pilots who flew them were both Enlisted and Officers, more often than not they were Enlisted Men, but as you can see in this case they were Officers and a majority of them were Combat Arms Officers of the units they were assigned to, in this case they were Artillery Officers.

Here is this history of the Liaison Pilots:

I can answer both specific and general questions about U.S. Army, and Naval Aviation from 1913 to 1946, and WWII U.S. Airborne, to include key personalities, units, commands, and doctrines. My specialty is U.S. Aviation Badges (all Branches of the Service, from WWI to the Present), U.S. Airborne Badges and Insignia (from WWII to the Present) as well as Aviation Badges Insignia and Issued Flight Gear (flight uniforms, helmets, sunglasses, etc…), Airborne, and Infantry Badges and Insignia (from WWI to the Present), both authorized and unauthorized, of the period. I have access to a vast personal library of text (as well as text from others...such as museums), as well as all the actual original badges, insignia and most of the flight gear that are specific to this period of history.


I have over 20 year’s experience in collecting and cataloging WWI, and WWI U.S. Army Aviation, WWI, and WWII U.S. Naval Aviation, WWI and WWII U.S. Issue Aviation Flight Gear, and U.S. Airborne Badges, Insignia and Airborne Equipment. I was the former assistant curator at the Gen. Wm. C. Lee Airborne Museum, when I lived in NC. I have written histories of Wing Badges and Aviation Insignia for several manufacturing companies to include The Robbins Company, Bailey Banks and Biddle, and I am working on the histories for several other companies at the moment such as Bausch and Lomb Tiffany, Herff Jones and several others. I am a consultant on regular basis to many museums (including the U.S.A.F., U.S. Army, Private and Public Museums, the Institute of Heraldry as well as the Department of National Defence and the Canadian Armed Forces), and I am regularly called upon to authenticate U.S. Aviation Badges, Insignia and Flight Gear (all Branches of the Service) for Fine Auctions Houses such as Bonham’s and Butterfields, and Sunglass manufactures such as Including Bausch & Lomb and Luxottica (vintage verification)...and many others.

I am perusing an advanced degree in history (Ph.D.), with a concentration in WWI and WWII U.S. Aviation. I am a U.S. Army Paratrooper and I am a Qualified and Rated Aviator.
