Alongside the standard PLCE webbing sets were a number of specialist rucksacks and carriers for particular pieces of equipment. Radios were one of those items that needed specialist carriers and tonight we have an example of the rucksack issued for use with the 320, 350, 351, 352 and Cougar radio systems:This large pack is made of DPM infra-red resistant Cordua nylon and is fitted with a pair of padded shoulder straps, a padded backrest and a waist belt to help support the weight of the radio:Zips are provided to allow two 10 litre PLCE bergan side pouches to be attached to the pack to increase capacity, and a further small pocket for a spare battery on the bottom of the front piece. This is secured with a black plastic nexus fastener and Velcro to secure the pocket flap:The main compartment of the pack opens with a long single zip that allows the whole pack to open up into two parts. The main, padded, part has a selection of securing straps to allow the different radios to be secured inside:With the 320 set, the radio sits above, with the battery stowed beneath:The lid portion has a small pocket to allow a folding aerial to be stored here:A single label is sewn inside with NSN number and details, sadly badly faded in this example:Of all the radios carried in this rucksack, the 320 is probably the best known- part of the Clansman family of high frequency radios introduced in the mid-1970s that lasted in service until the 2000s. The 320 could be carried with a (not very) light metal frame carrier or in a rucksack such as this one which was presumably much more flexible and comfortable for use in the field. The metal GS pack frame weighed 3.5kg, this rucksack just 0.5kg so there was a clear advantage in the field to using the lighter fabric rucksack.
