4.	Intelligence:
		(1.	Prior to operation:  See Intellignece annex to OPORD 5-67  
(OP TUCSON DELTA) 1st Bde, dtd 10 Feb 67.
		(2.	Enemy situation during the operation:  The area was heavily 
mined.  Many mines were found at likely river crossings, roads and likely base areas.  
Few enemy contacts were made with only one encounter being of significance.  This 
encounter involved Trp B.  On the evening of 16 Feb an element of Trp B was ambushed 
by the VC.  Re-enforcement was prompt and the enemy element suffered 7 KIA (BC) and 
the loss of wpns and equipment.

	a.	Weather:  Weather during this operation was hot and dry with cool 
evenings.

	b.	Terrain:  Terrain in the area of operations consisted of heavy 
jungle in part with numerious clearings bordered by unfordable creeks.  The only 
easily traversable areas were the clearings and the main trails.  (See Overlay)

5.	Mission:  1/4 Cav moves by road to Minh Thanh.  Secures movement of and 
a base for seven batteries of arty, occupies blocking psn YOKE, and prepares to 
commit battlefield relief force in 2/28th Inf sector on order.  1/4 Cav completed 
all missions assigned.

6.	Concept of Operations (extract from OPORD):

	a.	Maneuver:  1/4 Cav task force positions forces in Minh Thanh on 
order for blocking mission in AO YOKE and escorts arty, employing A, B, C, D Trps 
1/4 Cav, C/2/34th Armor, and A/5/2 Arty.  This operation will be conducted in two 
phases:
		(1.	Phase I (positioning 12 Feb):  1/4 Cav moves to Minh Thanh 
escorting 2/33d Arty.
		(2.	Phase II (Search and Destroy 13-14 Feb:  1/4 Cav Task Force 
secures arty base #3 (XT660579) and blocks in AO YOKE.

7.	Execution:

	   12 Feb:  1/4 Cav TF moved to Minh Thanh escorted 2/33d Arty.
           
	   13 Feb:  Trp B cleared Hwy 13 and escorted units to An Loc and Minh                         Thanh.  Other units continued proparations for movement to AO YOKE.              No enemy contact was made.
	   
	   14 Feb:  1/4 Cav TF moved to blocking psns and secured movement of and 
base for arty.  No enemy contact was made, however two tanks were damaged and one 
M113 completely lost due to enemy AT mines.
	   
	   15-17 Feb:  Secured arty base III, cleared and secured roads, conducted 
S&D operations in AO YOKE.  (See O/L attached).

8.	Support:
	
	a.	Field arty support was provided by 1/5, 2/33, and 8/6 Arty batteries 
of the 1st Inf Div Arty.  Continuous use of arty support was made by the 1/4 Cav in 
preparation defensive fires, recon by fire, illumination and harassing and 
interdiction.  The most important single contribution by the arty occurred on the 
evening of 16 Feb when B Troop 1/4 Cav was ambushed by unknown number of VC on the 
Minh Thanh/Michelin Road.  Batteries A/2/33, D 1/5th and B/8/6 arty fired a total of 
859 rds of 105 and 155 in support of Troop B. This fire was directed by B Troop's 
forward observer "Dynamite 92 through Drumfire 50B, one of the division arty air 
observers who got into the air over the action immediately.  Arty support provided 
during TUCSON DELTA was of the highest quality in responsiveness and accuracy.  

	b.	7th AF provided Tac air support. Prop and strikes were both 
preplanned and on call.

9.	(C)  Results: 

	a.	US Casualties:  17 WIA, 3 NBC's.

	b.	US Equipment Losses:  5 M48A3 tanks damaged, 1 M113 total loss, 
1 M113 damaged, 1-2 1/2 ton truck destroyed.

	c.	VC Losses:  8 KIA, (BC), Equipment: 4 wpns, 630 rds of ammo, 
12 AT mines, 24 AP mines, 7 bags of rice, 6 BA batteries, 9 hand grenades, 
1 B-50 AT rocket w/fuse, 300 ft commo wire, 3 rds of 105mm, 8 bobby trapped 
CBU's, 1 document, four 30 rd magazines.

10.	(C) a.  Logistics:  Logistical resupply was accomplished by use of land 
lines of communication from Minh Thanh.  Minh Thanh logistical facilities proved 
inadequate initially for support of their units primarily in the field of Class V.  
Inadequate stocks were initially on hand of 7.62 MLB 4 &1.   Aircraft for aerial 
resupply were difficult to obtain.  These problems were largely eliminated by the 
3d day of the operation.  The water point operated at Minh Thanh was impractical 
for all units to use due primarily to excessive turn around time and long waits 
at the water point.  This problem was alleviated when the squadron began using a 
fuel transfer pump to pump stream water into water tanks where it was chlorinated.  
     
	b.	Maintenance:  Vehicular maintenance was excellent using the 
recently established consolidated PLL vehicle located in the CP area.  Repair parts 
were readily available under this system.  The overall maintenance posture was good 
despite the extensive damage caused by mines.

	c.	Treatment of Casualties:  Numerous minor fragment and blast injuries 
from mine incidents were treated at the forward aid station.  One accidental 
drowning occurred.  Attempts at resuscitation were unsuccessful.  No other unusual 
problems were noted. 

	d.	Communications:  Due to distance of operation from Pui Loi base, 
direct communications between sqdn CP and base station was cut out during the day.  
This problem was solved by setting up a retransmission station at Trp C base in Lai 
Khe.  1st Platoon, Trp A frequency to be compatable for retransmission of both the 
logistics and command nets so Trp A's 1st plt was given the squadron operations  
frequency.   "Cricket" an air outfit, interfered with the log push; as yet, there 
has been no action on this by higher authority.  The division signal officer stated 
that we share the frequency and it will not be changed unless the interference get 
worse.  Subsequent report indicated that the XUAN LOC station would change 
frequencies.  

	e.	Medical Evacuations:  All evacuations were by supply helicopters or 
Dust-Off.  The above mentioned decease of a drowning victim was evacutated by routine 
dustoff.  No evacuation problems were encountered.

                    	  A/5/2..........    24                24

The shortage of personnel to make 5 man crews for each track remains a constant problem.

11.	Special Equipment:  None.

12.	Lessons Learned and Conclusions:

	a.	Areas previously occupied by US combat vehicles are likely to be 
heavily mined.  This was the case at Arty Base III.  Numerous AT mines were found 
on the roads, shoulders of the roads, and adjacent to the roads out to 30 meters.  
Such area should be thoroughly swept by mine detector teams and should be completely 
traversed by a tank prior to occupancy by other vehicles.  In addition, several 
casualties (arty personnel) were sustained as a result of personnel gathering 
together too close to the vehicles moving through the area.  A mine was detonated by 
a passing tank which (mine) injured five arty officers standing together nearby.  
The particular mine was the third or fourth that exploded withing the immediate area 
over a one hour period.

	b.	Regular vehicular movement over a particular jungle road invites 
ambush.  For several nights prior to the ambush of a three vehicle group (Trp B), 
mech inf unit periodically ran the same road.  Armored vehicles only should be run 
when ambush is likely (one truck was destroyed by a VC anti-tank wpn) and a strong, 
armored reaction force should be only minutes away from the area of likely ambush.  
Such was the case in this particular incident and the VC probably suffered far more 
casualties than the seven body count found the next morning.
