This large military training complex is centred at TR 0388 1784, between Invicta Road to the north, and Wickmaryholm Pit and Abnor Pit to the south. It extends across an area measuring approximately 1.5km east to west and 1.2km north to south. As is often the case with these training sites; it was situated on the coast so that misfired rounds could fall into the sea beyond the range without causing any harm or damage. Vertical aerial photographs of 1940 show a probable Second World War rifle range orientated north-east to south-west. It is centred at TR 0384 1768, and extends across an area measuring approximately 87m wide by 588m long. A series of targets in the form of structures, banks and trenches are visible at intervals along the length of the range. A track or small road runs down the north-western length of the range. It is bordered on its south-eastern side by a fence. This firing range has been interpreted as dating to the Second World War. However, it is also possible that it originated in the First World War, or the inter-war period. By the time of the vertical aerial photographs of 1946, the earlier rifle range appears to have gone out of use. Although some of its earthworks and structures were still extant, it has been overlain by the small railway track of a Second World War Armoured Fighting Vehicle (AFV) range. Tanks would have driven around a triangular track at the north of the site (centred at TR 0377 1829), while firing at moving targets on a system of tracks to the south (towards the sea). The system of tracks for the moving targets forms a complicated zig-zag arrangement in plan view. Narrow tracks or rails are just visible on the vertical aerial photographs of 1946, flanked on either side by banked-up shingle. Six blockhouses adjacent to various points of the trackway may have housed equipment which controlled the moving targets. These structures were protected by substantial banks of shingle piled-up over the top of them. At TR 0405 1794 on the eastern edge of the range, a single line of the small railway track branches-off north-eastwards across the neighbouring fields. This is most clearly visible on a vertical aerial photograph of April 1946. This appears to lead to a large rectangular shed, presumably for storage of the targets and other equipment. From this point (TR 0439 1829), another single line of track leads south-eastwards towards the neighbouring Second World War AFV range to the east (Monument Number 1538532). A further length of the small railway track appears to lead north-westwards. However, this is well beyond the boundary of the SE RCZAS NMP project area and was therefore not included in the transcription results of this survey. The latest available vertical aerial photographs of 2007, together with the information on the current Ordnance Survey maps show that part of the AFV range is still in use today. Although some parts of the range have fallen out of use and the railway tracks have been removed; the banks alongside the tracks are still clearly visible as extant earthworks. A few of the structures of the earlier possible Second World War rifle range are also still standing (1-4).
