The M551 Sheridan was an Armoured Reconnaissance/Airborne Assault Vehicle which entered service in the US Army in 1967. Within the next few years, the upgraded M551A1 was rolled out, which featured a newly installed laser measuring system, equipped ballistic computer and environmental sensors. The TTS (Tank Thermal Sight) it was equipped with was the same AN/VSG-2B unit featured in the M60A3 TTS.
This "2 in 1" kit from Rye Field Model allows you to build the tank in either its M551A1 or M551A1 TTS form. The tracks are easy to assemble "Link & Length" type, and clear parts, photo-etched parts, and decals are included so you can recreate the M551A1 in all its glory.
