The RBY Mk 1 is a light armoured reconnaissance vehicle that was produced by the RAMTA Division of Israel Aircraft Industries. RBY is an anglicized acronym for "Rechev Ben-Yaacov". "Rechev" is Hebrew for "vehicle" and "Ben-Yaacov" is the last name of the creator of the vehicle, Yitzchak Ben-Yaacov (1919-2011).

The M40 recoilless rifle is a portable, crew-served 105 mm recoilless rifle made in the United States. Intended primarily as an anti-tank weapon, it could also be employed in an antipersonnel role with the use of an antipersonnel-tracer flechette round. The bore was commonly described as being 106 mm caliber but is in fact 105 mm; the 106 mm designation was intended to prevent confusion with incompatible 105 mm ammunition from the failed M27. The air-cooled, breech-loaded, single-shot rifle fired fixed ammunition and was used primarily from a wheeled ground mount. It was designed for direct firing only, and sighting equipment for this purpose was furnished with each weapon, including an affixed spotting rifle.
