14.  (/)  COMMANDERS ANALYSIS:     The VC TET Offensive largely negated the pacification 
effort in the 2d Brigade Area of Operations.  Rather, all military efforts were redirected 
toward the destruction of the VC forces that infiltrated the SAIGON, THU DUC, LAI THIEU, 
and CHAU THANH area.  The Brigade was able to dominate the area and prevent large troop 
movements by following a policy of flexibility, response, and total area coverage.  The 
Brigade maintained a flexable tactical posture and outlook.  For example, when a particular 
method or area of operation ceased producing results, a unit was moved to a different area 
using another technique of employment.  The Brigade responded immediately to all hard 
intelligence. Thus preventing the VC from "getting set" for an offensive action.  A 
combination of the above, prevented the VC from moving large units through the Brigade Area 
of Operations during superb.  Each contact during this period was executed in an aggressive 
and professional manner.  The Cavalry demonstrated it's ability to accomplish any mission 
assigned, and accomplish them in an exemplary manner.

15.  RECOMENDATIONS:

	a.	Cavalry elements work extremely well in flushing out insurgents in jungle areas 
where they have a clear base from which to work.  They are able to move through the area 
rapidly and destroy anything in their path.

	b.	Use of the "Block" formation, with all tanks forward crashing jungle, proved most 
valuable.  The ACAVS followed the tanks, providing security and command.  This produced 
maximum fire power to the front, the most likely point of contact.

	c.	It was discovered that all areas capable of concealing large groups of VC must be 
continuously screened to prevent VC build-up.  This is particularly true of areas where 
US or ARVN forces do not normally operate.  The area to the south of  PHU LOI 
(XI908101 - center of mass) is a good example.
