(OKLAHOMA NATIONAL GUARD)
Before the Korean War the 45th Infantry Division had its headquarters in Oklahoma City, Oklahoma. It was federalized on 1 September 1950 and sent to Fort Polk, LA, for training and to fill out its ranks. Training completed, it deployed to Japan in April 1951 for further training and went on to Korea 28 December 1951, where it replaced the 1st Cavalry Division. After initial problems when it first went into combat, the 45th Infantry Division went to compile a good combat record.
The division consisted of:
- Division Headquarters and Headquarters Company
- 179th Infantry Regiment
- 180th Infantry Regiment
- 279th Infantry Regiment
- Division Artillery
158th Field Artillery Battalion (105mm)
160th Field Artillery Battalion (105mm)
171st Field Artillery Battalion (105mm)
189th Field Artillery Battalion (155mm)
145th Antiaircraft Artillery Battalion
- Division Troops
245th Tank Battalion (Medium)
120th Engineer Battalion (Combat)
45th Reconnaissance Company
- Division Special Troops
120th Medical Battalion
45th Signal Company
700th Ordnance Maintenance Battalion
45th Quartermaster Company
45th Military Police Company
45th Replacement Company

Bloody Ridge: a Quintessential Battle of the Korean War
by Bevin Alexander,
Background: In the summer of 1951 positional warfare had come to Korea. The Eighth Army commander, James A. Van Fleet, ordered 2nd Infantry Division of X Corps to eliminate a sag in the line, in the high Taebaek Mountains of eastern Korea. The original target was Hill 983, north of Inje.
On August 18 , the ROK [Republic of Korea] 36th Regiment of the 5th Division, now attached to the U.S. 2nd Division, attacked Hill 983, southwest of the Punchbowl, the big two-mile-wide and three-mile deep mountain mass that was to acquire the name of Bloody Ridge from Stars and Stripes, the service newspaper.
The preliminary to this assault on Hill 983 was a days-long concentration of artillery fire which gradually eliminated practically every trace of vegetation upon the ridgeline, turning it into a brown landscape with skeletons of trees clawing the air. The ROKs attacked frontally up the fingers leading to the peak. The ROKs quickly established the pattern of battle that was to predominate in Korea for the next two years in hundreds of battles, engagements and sorties on mountains and ridges all across the front. The heavy artillery bombardments and air strikes had eliminated trees and underbrush, but had not destroyed the communist bunkers or all the thick minefields protecting the emplacements. The bunkers, constructed of heavy timbers, and usually covered with deep layers of rock and earth, were so massive that generally only a direct hit by the heaviest-caliber artillery was able to destroy them. Such direct hits were difficult, because the bunkers were hard to find in the torn-up ground. The most effective weapon against them was the 155mm Long Tom rifle. There were relatively few Long Toms available, and they could not always be placed in position for direct, low-trajectory fire. As a result, as soon as the ROKs got within range of the bunkers, the North Koreans struck at them with automatic-weapons fire and clouds of hand grenades, which they threw or rolled down the ridgelines at the attacking troops.
After five days of repeated frontal assaults against Bloody Ridge, the ROKs finally took it, but then had to withdraw because of heavy NK [North Korean] counterattacks. General [ Clark L.] Ruffner [2nd Division commander] had to commit parts of 2nd Division’s 9th Regiment to support the ROKs, but still the North Koreans refused to budge. The heavy casualties the ROK 36th Regiment suffered led to a sharp decline in morale, and on August 27 some units of the regiment broke and ran. This spread panic among parts of the 9th Regiment as well.
The new X Corps commander, Major General Clovis E. Byers, decided to apply pressure against the Reds across the whole corps front in hopes of forcing the enemy to disperse his firepower and prevent the steady buildup of troops on Bloody Ridge. He assigned the ROK 5h Division the mission of seizing the northwest rim of the Punchbowl and directed the 1 st Marine Division to capture the northeast rim. The 2nd Division meanwhile got the assignment to take Bloody Ridge, while the ROK 7th Division was to attack and capture terrain to the west of Bloody Ridge.
The marines were fortunate in attacking while NK units were in the process of being exchanged, and the leathernecks’ forceful assaults carried through and won control of the northern lip of the Punchbowl.
The 2nd Division’s attacks on Bloody ridge were again direct assaults. Although they were fierce and sustained, they failed to dislodge the North Koreans. The leading unit, the 9th Regiment, suffered heavy casualties, but could not drive the NK defenders away. Brigadier General Thomas E. de Shazo, who had taken command of the 2nd Division temporarily, laid out a double-envelopment plan, using the division’s 23rd and 38th Regiments, while the 9th Regiment continued the direct assault on the ridge. On September 4 and 5 the resolution came suddenly: the North Koreans, weakened by heavy losses, evacuated Bloody Ridge, leaving the bodies of five hundred dead comrades on the heights. In almost three weeks of fighting, the ROKs and Americans had suffered more than 2,700 casualties, while the communists had sustained an estimated 15,000.
Infrared Sniperscope M3
The Sniperscope evolved from the M1 of WWII, with an effective range of about 70 yards, to the M2, with a range of about 100 yards. Both of these used vibrator power supplies to convert 6 volt battery levels to 4250 volts for the image-viewing tube. IR rays are focused on the image tubes, causing electrons to be emitted, which are then accelerated and strike a fluorescent screen, converting the sub-visible-light image to the visible light range, showing all objects as various shades of green. Besides enabling detection of enemy movement, and placing full-automatic fire upon them with complete surprise, IR units facilitate night communications between nearby units. Simple, pre-determined coded signals from a flashlight with an infra-red filter could be detected up to 500 yards. The M3, actually available for the Korean War, used 20,000 volts, had an effective range of 125 yards, and could detect ir-flashlight signals up to 1 mile.
The US Carbine, Caliber .30in, M3, or T3, was an M2 carbine with suitable mountings prepared on the receiver to take various models of infra-red night-sighting devices, and an M3 flash hider. No open or conventional sights were provided. The M3 carbine, (its development title was T3), was produced in limited numbers as a semi-prototype. Only about 2100 were manufactured compared to 5,510,000 M1 carbines, 150,000 M1A1 carbines and 570,000 M2 carbines.
However, the vastly improved Sniperscope M3, with almost double the effective range of the M1, with a less vulnerably located IR light source, and with the T23 flash hider was available at about the start of the Korean War, and would have had a deadly effect in the enemy staging phases of most night actions. Supplying only the M3, and in quantity, would have made the value of the weapon much more obvious, particularly if done before we faced the CCF so as to enable proper training.
