(17) During this time, two CH-46 from 1st MAW were in direct support of the


b. Four aircraft were lost as the result of enemy ground fire. The following is a resume of

each incident.

(1) 27 April 1967. An early extraction was programmed for a RECON patrol due to

enemy contact. The first recovery aircraft extracted two of the five patrol members

by hoist. The second recovery aircraft was over the pick-up zone but received heavy

fire and was shot down. No injuries to the crew. The crew and RECON patrol

members established a perimeter, ambushed approximately twelve VC. A Ranger

company was committed and joined up with the downed personnel. During the

assault of the Ranger company, a Marine CH-46 crashed, but had no injuries.

(2) 14 May 1967. During an infiltration, an UH-1D was hit by enemy fire which caused

the aircraft to execute and emergency landing. During the recovery operation, the

second recovery aircraft received fire in the pick up zone and crashed. The crew

chief was injured in the crash. The recovery operation was completed under flares.

(3) 21 May 1967. During the attempted extraction of a Roadrunner patrol, an armed

helicopter was shot down. The aircraft was destroyed by fire and an explosion.

Signal panels were observed near the aircraft. The gunner was extracted that day.

The aircraft commander and crew chief were spotted and an extraction was

attempted, however, the aircraft received automatic weapons fire and aborted. The

gunner of the recovery aircraft was killed by enemy ground fire. On 22 May, a

Ranger company was committed and located the crew chief. A search of the crash

site and area revealed no human remains. On 23 May, the Ranger company located

the aircraft commander. The pilot is listed as MIA. During the combat assault on 22

May, a Marine CH-46 helicopter was shot down. No injuries to crew or troops.


a. Emphasis of time factors during extractions. During the previous operations and especially

during this operation, a great deal of emphasis was placed on the selection of extraction

landing zones. A review of the length of time normally required to complete an extraction

is listed below:

(1) Touchdown landing in the LZ 6 to 8 seconds

(2) Ladder extractions 3 to 6 minutes

(3) Hoist extractions 8 to 15 minutes

(4) McGuire Rig extractions 10 to 20 minutes

(This method was not used during this operation)

b. Search and rescue operations (SAR). In future Operations, prior to the first infiltration,

the coordination should be completed for any SAR operation. This would include

establishing alert channels with the "Jolly Green Giant" and the elements of the supported

unit that could provide assistance. Also, to be able to utilize the US Air Force "Speaker"

aircraft is a very valid requirement. It was proven during this operation that personnel on

the ground could hear the directions given from the aircraft. If this coordination is

established prior to the operation, a much faster reaction time can be expected.


a. Night extractions: During this operation, a total of four night extractions were performed.

It must be emphasized that each were under emergency conditions. The following factors

were evident after the successful completion of the four night extractions.

(1) In each instance, the recovery flight was able to become familiar with the area during

the remaining daylight that existed. This enabled the armed helicopters to be able to

establish their protective cover orbits and the recovery aircraft to observe the

condition, location and unusual characteristics of the landing zones.

(2) In each instance, the rapid reaction of the recovery elements and the armed helicopters

was instrumental in the successful completion of the operation. In two instances, a large

volume of enemy automatic weapons fire was received which included large caliber

automatic weapons. In each case, the armed helicopters suppressed or silenced the fire.

(3) During the two night extractions which were conducted with the aid of flares, the initial

orientation of the recovery flight was difficult. To suddenly have a tremendous amount of

light causes orientation problems, however after a few minutes of adjustment, there was

no further difficulty. The biggest factor in the short orientation time was the fact that the

recovery aircraft had become familiar with the area prior to darkness.

(4) In each operation, the terrain favored the operation. The areas for extraction were

well defined and easily located. However, obstacles or the steep slopes present in

three of the landing zones prohibited landing and rope ladders had to be used for the

pick up. The time involved on this type of pick up is excessive and at a maximum,

only four to five people could be picked up at a time.

(5) The complete understanding between the aviation and ground personnel with each

others procedures was the key to the success of the night operations. This came as a

result of continuous operations over a long period of time and familiarity with the

capabilities and limitations of each other.

The successful completion of the night extractions may result in a temptation to rely

on the method as a normal procedure for extraction. One of the more obvious

disadvantages of night extraction is that after the reconnaissance element had

departed, the infiltration landing zone and then requires an emergency night

extraction the recovery element will be totally unfamiliar with the landing zone or

the area. Another disadvantage is that during an emergency extraction, no time is

available to evaluate or prepare the LZ. To attempt the extraction with the use of

flares presents similar problems but could conceivably be accomplished.

The largest obstacle in the night extraction technique is the insufficient amount of

training and proficiency on the part of the aviation and patrol elements. With the

usual minimum amount of time for training allotted between operations, this

procedure cannot be covered adequately for the elements concerned. Training

has been given previously for familiarization but on degree of proficiency has

been obtained. It has been firmly established during this operation that the

technique is a valid EMERGENCY procedure.

b. Photo coverage of the area of operation. During the latter stages of the operation, the

increased photo capability eliminated a lot of time usually taken during the aerial

reconnaissance for patrols and ranger operations.

c. "Dummy" extraction. It is proposed by the aviation element to consider executing

"dummy" extractions with the purpose of aiding a patrol to be able to continue its mission

even though it has been compromised. The procedure would be to locate the patrol and

select a landing zone about five hundred meters from their location; approach the area

with a normal extraction flight; conduct an armed helicopter pre-strike and commit a

"dummy" extraction aircraft. This could not be used often but it might aid the patrol to be

able to continue its mission.
