Call signs of the Mobile Riverine Force were clever names meant to confuse the enemy regarding the actual names and locations of units when communicating over the radio. This initial call sign list was contributed by member Ed Gorczyk “Dragonfly A-3.” These signs were used in the 1967-68 time period. Thanks Ed for getting this started. You may be aware of others or you can fill in some of the blanks below. If so, please email webmaster Mike Harris at the email address below and I’ll make the additions/corrections as necessary. You may also remember different call signs from different years. If so, please signify the year. We are missing several ships and a lot of 9th Army unit call signs so please provide those and we’ll get them added. Thanks to all who have provided additions and/or corrections to the list. Your help is much appreciated.

* Notes to Army Call Signs:

Thanks Ron Menner for this excellent information on breaking down Army Call Signs. The following pertains to the 3rd/47th but could easily describe other Army units by replacing the call sign. For example, Langley was the call sign for the 3rd Battalion/47th Infantry/9th Infantry Division. Numbers were added to call signs to indicate the unit commanders. For example,
Six was used for Commanding Officers (Langley Six was LTC Blackie Bolduc),
Five for Executive Officers or Second in Command
Four for Supply/Logistics Officers
Three for Operations Officers
Two for Intelligence Officers
One for Personnel Officers

Company Commanders were, for example,
Langley Alpha Six for A Company, 3rd/47th
Langley Bravo Six for B Company, 3rd/47th
Langley Charlie Six for C Company, 3rd/47th

Operations Centers were designated Three Three. Examples: Langley Three was the operations officer of the 3rd Battalion, 47th Infantry. Rifle platoons were identified for example, as Langley Charlie Three Six which was the Third Rifle Platoon Leader in C company of the 3rd Battalion, 47th Infantry. At the platoon level, Five would designate the Platoon Sergeant.

Other interesting Army nomenclature:
Crossed SabersCavalry
Crossed CannonsArtillery
Crossed PistolsMilitary Police
Crossed RiflesInfantry
Flaming PotOrdnance
Wheels with SpokesTransportation
Lightning BoltSignal
!!Battalion or Squadron
!Company, Troop or Battery

While there are exceptions to the rule, a two-number designated unit such as the 47th infantry denotes it belongs to a division commanded by a two star General. A three-number unit such as the 205th Military Police belong to a Corps commanded by a three-star General, and a four-number unit such as the 4077 MASH (Hawkeye Pierce’s unit) the 4077 Mobile Army Surgical Hospital belongs to the Army Commander, a four star General.

Helicopter Support of the 9th Infantry:

The 191st was stationed at Bearcat from 5’67 til 8’68, and then moved to Dong Tam. They provided combat support for the 9th Infantry Division and the entire MRF, frequently landing on the Benewah and at Nha Be Naval base for rearming, refueling, etc. Because of their extraordinary combat record they were also called upon to support the Naval Seal teams, the 25th Inf. Division, the 1st Inf. Div. and the 199 Light Inf. Brigade.

The 191st Assault Helicopter Company was somewhat typical of helicopter support for the 9th Infantry. It was composed of 4 platoons. Two “Slick” platoon consisted of 10 helicopters each which inserted, transported, and extracted troops. The white and yellow tail markings designated the platoon so the troops would have an easy way to identify them coming.

The third “gunship” platoon was composed of eight gunships ( armed helicopters, each with two 8-barrel miniguns with 1,000 rounds of 7.62 per minigun, 6 rocket pods, and two door gunners with hand-held M-60 machine guns with 4,000 rounds per machine gun. The gunships provided protection to the slicks when they were inserting, or picking up, troops. They also provided fireppower for other units, when needed.

The mechanics who took care of these ships were the fourth platoon.
