Among Anti-tank weapons employed by Rangers, especially in modern times, none are as storied and despised as the M67 90mm Recoilless Rifle, used by 1st and 2nd Ranger Battalions throughout their existence, prior to the creation of the 75th Ranger Regiment in 1985.

The 90 was carried by a two man AT team. The teams trained together as part of a weapons platoon in each Ranger Company. For operations, the AT teams were attached to a Platoon. In heavily wooded areas, the responsibility of the Assistant Gunner was in assisting the gunner in manuevering the "stovepipe", as it was affectionality called by some, through the morass of vegetation typically encountered.

The greatest success story of the M67 was the defeat of two lightly armored vehicles approaching the tarmac at Point Salines Airport on the island of Grenada. The two vehicles were manned by Cuban soldiers who intended to attack the Rangers of 1st and 2nd Ranger Battalions who had just landed to take the island.

There were four rounds created for the M67. These were Anti-Personel flechette rounds, High-Explosive, Anti-Tank (HEAT) rounds, HE, and armor-piercing. The rounds typically favored by the Ranger 90 Gunners were the HEAT and AP Flechette rounds. The AP Flechette rounds have a unique distribution pattern, similar in principle to a shotgun round, where increased distances to the target causes dispersal of the individual flechette rounds. The 90s were phased out by the Army in favor of Carl Gustav Ranger Anti-Armor Weapon (RAAWs) in the late 1980's. The 90 ammunition proved expensive to acquire and maintain as there were very few units with a desire to use them.
