For what it's worth, this is the section from the source guide relating to the Borgward units. There are probably still things to add (and possibly to correct) but since the subject appears to be of interest, I'll post it here now:
[From chapter on Pz forces and armoured warfare - although it could end up with the engineer section instead.]
4.3. Remote-controlled demolition units:
Among the more unusual units used by the Germans in Normandy were three which operated remote-control armoured demolition vehicles known as Funklenkpanzer. These were equipped with the ‘Borgward IV’ heavy explosive charge carrier and Sturmgeschütz control vehicles. One of the units also had five Kingtiger tanks. The units were attached to three different panzer divisions.
4.3.1. General works and intelligence reports:
‘Independent assault gun company’. This Canadian intelligence report describes the tactical use of Borgward explosive carriers and their control vehicles. See Part II of First Canadian Army’s Intelligence Summary No.34, issued 2 August 1944 (UK National Archives, WO 179/2606A).
Jaugitz, Markus (trans. Johnston, David): German remote-control tank units 1943-1945 (Schiffer Military/Aviation History, Atglen 1996: 50pp., illustrations). This is the English-language edition of the author’s Waffen Arsenal – Die Deutsche Fernlenktruppe 1943-1945 (Podzun-Pallas Verlag). The book describes the development and technical specification of the Borgward IV heavy explosive charge carrier.
Jaugitz, Markus (trans. Johnston, David): Funklenkpanzer: A history of German Army Remote- and Radio-Controlled Armor Units (J. J. Fedorowicz Publishing Inc., Winnipeg 2001; xii + 610pp., maps, illustrations). This book identifies the equipment employed by German remote-control demolition vehicle units in Normandy and describes their use in action (pp.366-99 and 457-8).
‘Radio-controlled demolition vehicles – Sprengladungsträger’. This is a detailed intelligence report about the characteristics of the Borgward IV, based on inspection of four abandoned vehicles of this type captured at Mouen, west of Caen (see section 4.3.3. below). The description is in Part II of British Second Army’s Intelligence Summary No.39, issued 14 July 1944 (UK National Archives, WO 171/221). Appendix D to the same report includes a drawing of one of the captured demolition vehicles, plus a sketch map showing where they and their control Sturmgeschütze were found.
‘Tactical use of the B.IV.’ This report is based on a captured German notebook, in which material relating to the tactical use of Borgward demolition vehicles was included. See Part II of British Second Army’s Intelligence Summary No.43, issued 18 July 1944 (UK National Archives, WO 171/221).
Zetterling, Niklas: Normandy 1944: German Military Organization, Combat Power and Organizational Effectiveness (J. J. Fedorowicz Publishing, Inc., Winnipeg 2000; ix + 462pp., illustrations). Pages 188-9 of this book provide information about German funklenkpanzer units that fought in Normandy during summer 1944. The same material can be found on pp.160-1 of the 2019 edition of the same work.
Three U.S. intelligence documents that describe the features of the Borgward IV can be downloaded free of charge from the following internet source:
http://www.sturmpanzer.com/Research/Library/intel.aspx. The reports provide detailed technical specifications and are illustrated with numerous photographs.
4.3.2. 301st Funklenk Battalion (Funklenk-Abteilung 301):
A company from this unit, which was equipped with the Borgward IV vehicle, served with 2nd Panzer Division during the Normandy campaign.
‘B IV b radio controlled demolition vehicles’. This is a report on the use of Borgward demolition vehicles against Canadian troops at Verrieres, near Caen, on 31 July. Almost certainly, this engagement involved vehicles belonging to 301st Funklenk Battalion. The account is in Part II of British Second Army’s Intelligence Summary No.58, issued 2 August 1944 (UK National Archives, WO 171/222). It also appears in Part II of First Canadian Army’s Intelligence Summary No.56, issued 24 August 1944 (UK National Archives, WO 179/2606A).
‘Tactical employment of B4 equipment’. This is an account of an attack carried out against Canadian troops by a group of Borgward IVs on 31 July 1944. It contains much more information than the report mentioned immediately above. The material was extracted from 2nd Canadian Infantry Division’s Intelligence Summary No.6 and appears in First Canadian Army’s Intelligence Summary No.33 of 1 August 1944 (UK National Archives, WO 179/2606A).
Verwicht, Alain: “Unites et Materials: La 2.Panzer-Division, 1 Juin 1944”, in Panzer Voran! Number 2, 1999, pp.22-25. This French-language article pays particularly close attention to 301st Funklenk Abteilung, one of whose companies was attached to 2nd Panzer Division at the start of the Normandy campaign.
4.3.3. 315th Funklenk Company (Panzer-Kompanie 315 (Funklenk)):
This Borgward IV unit was attached to 21st Panzer Division on D-Day. It was withdrawn from action in late June.
‘Fmn emblems - 315 Independent Assault Gun Company’. This short intelligence report notes the presence of knocked-out Borgward IVs and their controlling assault guns near Mouen, west of Caen. See Part II of British Second Army’s Intelligence Summary No.36, issued 11 July 1944 (UK National Archives, WO 171/221).
Three interrogation reports of members of this unit can be found in the UK National Archives. They provide interesting information about the organisation and equipment of the unit, and how its vehicles were supposed to be used in action. See WO 208/3590 (SIR 337), WO 208/3621 (PWIS(H)/2), and WO 208/3622 (PWIS(H)/22).
4.3.4. 316th Funklenk Company (Panzer-Kompanie 316 (Funklenk)):
This Borgward IV unit was attached to the Panzer Lehr Division during the Normandy campaign.
Irrgang, Astrid: Leutnant der Wehrmacht: Peter Stölten in seinen Feldpostbriefen – Vom richtigen Leben im Falschen (Rombach Verlag, Freiburg 2007; 345pp.). Unfortunately, I was unable to see a copy of this book before completing this bibliography. According to Nicholas Stargardt’s The German War: A Nation Under Arms, 1939-45 (The Bodley Head, London 2015, pp.426-9), it is about a young German officer who served with 316th Panzer Company (Funklenk) in Normandy. Stölten was injured in a motorcycle accident in July 1944, but correspondence quoted in Stargardt’s book describes some of his experiences during the previous month.
Santin, Eric: “Été 1944: les Tiger de Châteaudun”, in 39/45 Magazine, Number 157-8, July-August 1999, pp.2-15. This article describes the fate of five Kingtiger tanks belonging to 316th Panzer Company (Funklenk), which were encountered by US forces in and around the town of Châteaudun on 16 August 1944, during the breakout from Normandy.
