Wireless Sets of the 1st Airborne Division at Operation Market-Garden

One perspective on a military operation can be to view it as an equilateral triangle, or Venn diagram, with the three points of the triangle, or circles of the diagram, being; 1. Communications, 2. Logistics, and 3. Intelligence, hopefully with all three elements in equilibrium. However, as seen by the ranking, without effective communications any military operation is in immediate peril.

During Operation Market-Garden all three elements were found to be seriously wanting, obviously placing the operational field commanders in serious peril from the outset of the operation. In his official after-action report MajGen Robert E. “Roy” Urquhart, O.C. British 1^stAirborne Division, was particularly vehement in his criticism of field communications. A direct quote:

“242. Royal Signals.

Communications within the Airborne Division and to the Base and the next higher formation need drastic revision and improvement. The sets at present in use are not satisfactory in all cases. The range attributed to sets was nearly always found to be greatly exaggerated.” (Author’s note: Given the English propensity toward understatement I would say that this is a comprehensively damning assessment.)

The basic radios in use during the operation were the Wireless Sets No.22, No.19HP,  No.18, No.68P, No.68 R/T, No.38 Mk II, and Wireless Sender no.76. The XXI Independent Company (Pathfinders) had their No.38 sets withdrawn just two weeks before the operation, and replaced with the vastly superior Wireless Set No.42.

A set: AM (1,5 - 2,5 W), MCW and CW (3 - 5 W), covers 2 - 8 MHz in two ranges (2-4,5 / 4,5 - 8 MHz), two mechanical presets. B set: VHF (telephony, 0,4 W) in the range 229 - 241 MHz. Pye introduced the W.S. 19 MK I transceiver in 1941, because of the frequency coverage of the A-set appeared to be too narrow, the MK II was introduced in 1942 with a coverage 2,0 to 8 MHz, split in two ranges. Later a special dial knob was introduced for easier tuning, which came with the Wireless Set 19 MK III, but was often mounted on the MK II sets.

They have been used in parachute drops as well as animal packed, Wireless Set No.76T stands for the tropicalised version.

Operation Market-Garden 75th Anniversary Encore Performance by King & Country Military Miniatures

The Red Devils are resurrected. What had been thought to be a Last Post for King & Country’s Market-Garden Series was premature. On the occasion of the 75^thAnniversary of Operation Market-Garden, the Battle of Arnhem/Oosterbeek, the company has issued an additional increment of figures, a new fighting vehicle, and an assault glider.

MG076 Planning Market Garden - Paralleling their set commemorating the 75^thAnniversary of D-Day, this is a 5 piece set depicting a large map board showing the overall operation and theArnhem/Ooosterbeek area, surrounded by four of the significant leaders of the operation; LtGen Frederick “Boy” Browning, LtGen Sir Brian Gwynne Horrocks, MajGen Robert  E. “Roy” Urquhart, and Polish MajGen Stanslaw Sosabowski.

 MG077 On The Road To Arnhem - Three Paras in route to their objectives, one carrying a Bren light machine gun, one carrying a PIAT and his rifle, and a third carrying the standard container with three rounds of additional PIAT rounds.

MG078 A Para with his rifle at the ready, standing beside a large yellow ARNHEM road sign.

MG079 A pair of Paras, one sitting with his rifle at the ready, the other with a STEN machine carbine, also at the ready.

MG080 A three figure "Bren Gun Section"

MG081 A two figure set titled "Going Into The Attack".

MG082 "The Arnhem Vickers Set"

 MG083 This set is a Humber Mk I Armoured Reconnaissance Vehicle with the tactical markings of the Guards Armoured Division, and includes the figure of LCol (Later Brigadier) J.O.E. “Joe” Vandeleur of the Irish Guards.

AIR101 Airspeed Horsa Assault Glider – Believe this to be a very limited edition (group of 5 models) in 1:30 Scale; Wing Span: 84cm (27.08in), Length overall: 64cm (23.20in) most likely in mahogany wood. Suffices this is a rather pricey model.

These figures are all excellent, accurate, and very realistic sculptures. It is truly unfortunate that an apparent significant change in the painters, sealed patterns, and quality control (or combination), used by King & Country has resulted in a major error in the colors used in the Denison smocks (particularly the light khaki tan and the brown). Using the definitive reference "DENISON British Airborne Specialist Clothing From WW2 To The Present Day", B. Wilson, Military Mode Publishing, Hitchen, Herts. 2013, ISBN 978-1-62620-184-2, this author has diligently tried, without success, to find a single smock with the same colour combination as the entire recently released series. The closest being on pp.74-75. All their previous figures in the Market-Garden Series had the colour spot-on. This fact has been further exacerbated by the multiple grouping of figures, as well as a significant sharp increase in their pricing.

The reader can judge for themselves based on the following two images:

In all fairness, I purchased one of Set MG082 as a comparative example, and either the company has modified their paint colours in the Denisons, or whoever is doing their advertising photography may want to modify their lighting/filters, or otherwise hone their skills, because fortunately in real life at least, the colours of that set aren't quite as bad as they appear in the published images.
