A. Air.
(1)
During period of 26-29 May 1967, no fixed wing aircraft were utilized.
Air Force and Marine A/O's were utilized daily throughout the period.
(2) On the morning of D+4, 12 fixed wing aircraft conducted a preplanned
LZ preparation of LZ Robin located in vicinity coordinates (BT 100210).
Strike was controlled by a Marine TAC/A in support of debarking 1st Battalion,
5th Marines units in vicinity coordinates (BT 100200). Strike was controlled
and supported by a four plane flight of Marine UHIE gun ships. The strike
effectively suppressed moderate sniper fire that was being received from the
area. Two A4 aircraft struck enemy sniper positions in vicinity coordinated
(BT 124225) which was hindering the advance of Company F. The enemy
fire was suppressed. The strike was controlled directly by Company F's
FAC Team. One of the A4 aircraft collided with the ground during his
second run on the target. Cause of the accident was undetermined.
(3)
On D+5 and D+6 Marine and Air Force observation aircraft were utilized extensively
by advancing 1st Battalion, 5th Marines units. On D+7 two F-8 and two
F-4 aircraft conducted a close air support strike on fortified enemy positions
in vicinity coordinates (BT 123324) in support of Company D. The strike
was controlled by an Air Force TAC/A in an O1 aircraft. Result of these
air strikes was one KBA, confirmed. Four A-4 aircraft conducted a close
air support strike at vicinity coordinates (BT 115325) against enemy positions
that were hindering the advance of Companies D and F. Five houses were
destroyed and 1st Battalion, 5th Marines units were able to sweep the area.
The air strikes were conducted by a Marine TAC/A in an O1 type aircraft.
During the night of D+7 and morning of D+8, six flights of F-4's, six flights
of F-8's and four flights of A-4's conducted continuous air strikes against
heavily fortified enemy positions, which were located between vicinity coordinates
(BT 095324) and (BT 086318). The strikes were flown in support of Companies
D and F who were engaged with a large enemy force. The strikes were
controlled by an Air Force C-47 DRAGON SHIP and Marine UH-1E gun ships.
Coordinating instructions and enemy/friendly position reports were supplied
by the Company D FAC. During intervals when fixed wing aircraft was
not on station, the DRAGON SHIP strafed the target area. One small-fortified
village was completely destroyed. 5th Marines AIO response to 1st Battalion,
5th Marines immediate requests for tactical air support on D+7 and D+8 was
considered to be outstanding. The timeliness and effectiveness of the
fixed wing air support provided to 1st Battalion, 5th Marines units contributed
directly to the successful accomplishment of the Battalion's mission.
B. Artillery.
(1) Artillery support until D+5 of UNION II was provided by Battery D, 2nd Battalion, 11th Marines. As 1st Battalion, 5th Marines continued the advance on D+5, support shifted to Battery W, 2nd Battalion, 11th Marines. Battery D, 2nd Battalion, 11th Marines again assumed the role as direct support on D+8 and continued to support 1st Battalion, 5th Marines until the conclusion of the operation. Operation "UNION II" was characterized by extensive use of preparation fires. The preparations were very effective and contributed to a noticeable lack of sniper harassment. Observed missions during the first 8 days of Operation UNION II were few due to insufficient target areas. On D+8 Battery D supported 1st Battalion, 5th Marines by firing continuous missions for Companies A, D, and F from 1100H until dark, with excellent effect on the target areas.
(2) H&I fires were used nightly during UNION II on avenues of approach,
mortar positions, assembly areas, harbor sites, areas of known VC activity,
and routes of communication and resupply.
(3) A total of 267 such areas were denied use to the VC. Artillery
support for Operation UNION II was excellent and contributed significantly
to the overall success of the 1st Battalion, 5th Marines.
C. Engineer.
(1) Engineer support for Operation UNION II was provided by the 1st
Platoon, Company "B", 1st Engineer Battalion attached to the 1st
Battalion, 5th Marines.
(2) On 4 June 1967 three separate caves and one tunnel complex were
destroyed by the engineers in the vicinity (BT 108316). All caves were
approximately 6 feet deep and 3-4 feet high extending 15 feet, 20 feet and
50 feet into the ground. The tunnel complex was 96 feet long and 3 to
5 feet high with wooden planks for decking.

charges were used to destroy these caves and the 29 ordinance items listed
in paragraph 11e.

12. Administrative Matters.
a. Supply.
(1) Resupply was effected by helicopter controlled by the 1st Battalion, 5th Marines HST with the Battalion Command Group. HST's were attached to Company A, Company C and Company D during Operation Union II. Company F, 2nd Battalion, 5th Marines did not have an HST and requests were relayed to the Battalion Command HST over the Tactical Air Request net. During the first three days of Operation Union II, one priority medical evacuation, one routine resupply and a troop lift for Company F were completed.
(2) From 30 May through 1 June one emergency medical evacuation and
one routine resupply were completed. On 2 June - 3 June six separate
medical evacuations, one emergency resupply and one routine resupply were
completed. Troop lifts for 2nd Battalion, 5th Marines and 3rd Battalion,
5th Marines were completed on 4 June and 5 June.
(3) The necessity of using the overcrowded Tactical Air Request net
for resupply and evacuation request for company forces was the only problem
encountered.
(4) The basic allowance of ammunition and 5 MCI was sufficient for sustained
operations by scheduling normal resupply every other day. This combat
load did not hinder the movement of the units.
b. Maintenance.
(1) Cleaning equipment for crew served and individual weapons was carried
by all units of the 1st Battalion, 5th Marines. There were no maintenance
problems during Operation Union II.
c. Transportation.
(1) Transportation for the 1st Battalion, 5th Marines units was limited
to the helicopter troop lift on D+4. The troop lift was completed with
no problems.
d. Communications.
(1) No significant problems were encountered with communications during
Operation Union II. Due to the terrain and distance it was necessary
to use the Regimental relay site at NUI LAC SON and a C-117 Airborne Radio
Relay during the initial stages of the operation.
e. Medical Evacuation.
(1) Medical support for Operation Union II was provided by company corpsmen
and by the Battalion surgeon and two corpsman with the Battalion Command Group.
On 2 June 1967 casualties were brought to the Command Group where medical
personnel rendered first aid and effected a triage for helicopter evacuation
to medical support activities in Chu Lai and DaNang. No significant
medical problems were encountered.
13. Special Equipment and Techniques.
(1) No special equipment or techniques were utilized during Operation
Union II.
14. Commanders Analysis.
(a) There was little or no contact with noncombatants. Thus, no
problems or special actions on CA/PSYWAR were required. NVA forces were
disposed in well prepared positions, emphasizing the requirement of a complete
fire support plan to include preparation, planned and on call fires.
(b) On one occasion the enemy was found to be hiding under straw mats
in an open field, and were detected by a Kit Carson Scout. The effective
utilization of Kit Carson Scouts is limited only by the imagination of the
Unit Commander.
(c) The enemy's employment of an irritant chemical agent did not effect
the combat efficiency of the 1st Battalion, 5th Marines, but it does illustrate
the enemy's ability to employ a variety of weapons.
15. Recommendations.
(1) That the tenets of proven combat principals continue to be emphasized
at all levels.
