I built this MRV combining files from the FV Series of Vehicles by bigwig_mark and the M113 APC variants by Captain_Ahab_62 on Thingiverse. Thanks to them for doing the heavy lifting. Currently this file is a WIP and untested, though I plan to print today on a Anycubic Photon printer to test.
This is intended for use in Miniature Wargaming for forces in the Team Yankee Free Nations Anzac Army. Keep an eye on my progress over at www.wargaming3d.com
Background: M113A1 Medium Reconnaissance Vehicle (MRV) - Full designation Carrier, Fire Support, Full Track M113A1 (FS) Scorpion Turret was an Australian variant similar to the M113 FSV, but using the turret from the FV101 Scorpion light tank, instead of the older turret of the Saladin armoured car, that the FSV had previously used. This turret was equipped with an Image Intensifier sight for the main armament. This II sight was the first effective passive night sight fitted to an Australian AFV, giving the MRVs a night fighting capability exceeding the Leopard AS1 and all other Australian AFVs of the period. Whilst fully amphibious, the MRV was also fitted with a light sheet-metal foam-filled trim vane and side pods. These pods and the trim vane were intended to provide additional flotation and stability on the water; they provided virtually no additional armour protection. Other changes included a modified driver's hatch which pivoted toward the centre-line of the vehicle instead of opening to the rear of the driver's hatch; this feature preventing the open driver's hatch being caught on the traversing turret, as well as the fitting of the British "boiling vessel", an electric vessel for boiling water and heating rations. As indicated by the designation change, the MRVs were roled as reconnaissance vehicles and issued to the Cavalry (medium reconnaissance) regiments, whereas the FSVs were originally issued to APC squadrons and used to provide infantry fire support.
