11th TRS arrives from Mountain Home AFB Idaho. RF-4Cs. Also at Udorn, Gen. Bond called a planning conference because of the decision to utilize A-26s in the Barrel Roll region. The conclusion was to increase operations in Barrel Roll in coming weeks and hit the enemy in their bivouac areas before they dispersed to attack friendly areas in the Sam Neua Province and attack the increased vehicle traffic.
 
Oct - Dec 1966
Dry roads permitted NV trucks to roll into Sam Neua Province with increased numbers. Richard Secord devised a plan to utilize Meo road watch teams commanded by Tall Man and Red Man. The men spoke English and were experienced in calling in strikes. Operation Night Watch was to interdict the trucks along Routes 6 and 65 with A-26 Nimrods based at Nakom Phanom. A-26s flew to Sam Neua Province nightly and their road watch teams and controllers directed aircraft to targets. In a week's time, Nov 2 to 9, A-26s destroyed or damaged 67 trucks, four antiaircraft guns, one bulldozer and killed 384 enemy troops including 154 troops identified as North Vietnamese. Many others were wounded. Traffic was at a trickle by 10 November along Routes 6 and 65 and Meo intelligence thoght enemy ammunition and rice supplies were low with about 20 trucks carrying the load at night in groups of five or six. Meo commanders believed the air strikes would prevent the enemy's dry-season offensive.
 
1 Nov 1966
Big Eagle A-26s were fragged for four sorties per night in the Barrel Roll area. A-26s worked in tandem with F-104s, A-1Es and Meo guerrillas on the ground. Roadwatch teams passed real-time intelligence to them about moving trucks and active truck parks along the Trail. November and December were moths when the North Vietnamese were resupplied, strengthened and launched offensives. A-026s were flying five sorties in the Steel Tiger area.
 
26 Nov 1966
A-26 sorties were reduced to seven per night, four in Steel Tiger and three in Barrel Roll. Bad weather sorties in the north were diverted to Steel Tiger.
 
29 Nov 1966
A large convoy of trucks was spotted by an A-26 crew in the Barrel Roll area. Capt Billy L. Green and navigator, 1st Lt Robert L. Tidwell (Nimrod 32) were flying an armed reconnaissance mission when they spotted truck lights about ten miles away. They discovered 15 trucks traveling southeast on Route 65 spaced at 300 meters with lights on. A scout car and three 10-wheel trucks were destroyed as they tried to escape.
 
Dec 1966
Road watch leader "Tall Man" was accidentally killed by his rear guard while enroute to base camp. The USAF flew 447 sorties in Barrel Roll during December destroying 31 trucks. A-26s flew 20 of the USAF missions amd were credited with 27 of the 31 vehicles reported. In Steel Tiger the USAF flew 2,546 sorties with 163 trucks destroyed or damaged. The A-26s were credited with 99 of the kills although they flew only 175 sorties.
 
Dec 1966
A-26A aircrews and support personnel began arriving PCS at Nakhon Phanom and the detachment officially became part of the Lucky Tiger force. The 606th ACS Commander, Col Harry C. Aderholt arrived 9 December 1966 and immediately began studying ways to exploit the A-26A capability in Laos. He was also interested in integrating T-28s into the interdiction system. By January T-28s were a part of Lucky Tiger.
 
25 Dec 1966
In Barrel Roll near Nong Het on Route 7, a convoy of trucks was active. Four strafing sorties destroyed or damaged 11 trucks plus POL fires continued to burn for four hours.
 
26 Dec 1966
Col. Aderholt addressed the effectiveness of A-26A operations under the Big Eagle concept. "From 1 Nov 1966 to 24 Dec 1966, A-26A aircraft of Det 1, 603d ACS patrolled in both Barrel Roll and Steel Tiger frequently aided by direct contact with road watch teams. They attacked targets of opportunity nightly. However thiws small unit has been unable to provide adequate covereage over operational areas throughout the hours of darkness. Road watch teams and photo reconnaissance continue to confirm heavy enemy traffic on BR and ST routes. It is important to note that these same sources reported complete stoppage of traffic for a short period of time on Barrel Roll routes when four A-26A sorties per night were fragged into this area 1-12 November 1966. Intelligence reports on 13 November indicated that all traffic had stopped after less than two weeks of harrassment by A-26A night armed reconnaissance."
 
Dec 1966
American troop numbers reach 400,000 in South Vietnam. Also U.S. fighters shot down 23 MiGs during 1966, 17 credited to the USAF while losing 9 aircraft, 5 USAF.
