It incorporates dual illumination technology using a combination of fiber optics and self-luminous tritium. This allows the aiming point to always be illuminated without the use of batteries. The tritium illuminates the aiming point in total darkness, and the fiber optic self-adjusts reticle brightness during daylight according to ambient light conditions. This allows the operator to keep both eyes open while engaging targets and maintaining maximum situational awareness. Designed to the exact specifications of the United States Marine Corps, the unique reticle pattern provides quick target acquisition at close combat ranges while providing enhanced target identification and hit probability out to meters utilizing the Bullet Drop Compensator.

Samutilar With the newer version, this stuttering is not as obvious. This is now the point of impact. Weapon stabilization is crucial, orientation is irrelevant.
The fundamentals of marksmanship are modified as follows:. Boresighting is a simple procedure that can and will save time and ammunition if the procedures outlined here are strictly followed. Arm the visible laser stops on the zeroing mark, the borelight is zeroed to caog weapon. Make adjustments to the M68 until the visible laser of the borelight is centered on the borelight circle on the meter boresight target.
What do you believe is the type of influence involved with persons converting religion to the radical kind? Designed to qrmy exact specifications of the U. A practice qualification must always precede an actual qualification. Qualification standards are the same for day and night.
When zeroing the M68, CCO at 25 meters, a designated impact zone must be identified on the meter zero target. Probably the biggest advantage the TWS provides is its ability to negate camouflage. The M68 is a parallax free sight beyond meters. Figure shows the close-combat optic training program. The BIS is adjusted for a meter battlefield zero to provide backup in the event an optic or laser device fails to function.
The preferred method of aiming using the M68 is to keep both eyes open, which allows a much greater field of view and makes scanning for targets much easier. Dry fire is done to allow the soldiers to make adjustments to the TWS. The back-up iron amy BIS can be boresighted to a new user to expedite meter zeroing. Placing the cheek on the stock weld to get a good sight picture after the M68 is zeroed at 25 meters is no longer necessary.
Are you sure you want to delete this answer? With these versions scanning must be done slowly in order to maintain a good thermal image on the screen.
Figure shows the current training program for these lasers. Target detection procedures for the M68 are the same as with standard iron sights. The borelight is seated properly when the mandrel cannot be moved any further into the muzzle and the mandrel spins freely.
This position of the borelight, and where the visible laser is pointing, is aco as the half turn position. Weapon stability is crucial in boresighting.
Align the meter boresight target with the visible laser of the borelight. After the target has been engaged, the laser is deactivated.
Practice qualification with the TWS is the same as day practice qualification with iron sights. The art of target detection at night is only as good as the soldier practices. The procedures for practice qualification are:. With lasers, the borelight allows the soldier to boresight and then engage targets, eliminating the meter zeroing procedures altogether. It amplifies reflected light such as moonlight, ary, and sky glow so that the viewed scene becomes clearly visible to the operator.
Equipment Personal Equipment Optics. Adjusting the brightness, contrast, and polarity helps enhance the thermal cues of a target, allowing for quicker detection and identification. During the dry-fire exercise soldiers acquire a sight picture on all exposed silhouette targets prior to conducting the field-fire scenario. When the target aarmy detected the soldier orients his weapon around the base of the target, activates his laser, and walks the laser to the armg mass of the target for engagement.
At ranges of 50 meters and beyond, the effects of parallax are minimal. Before beginning a night marksmanship program, soldiers must qualify on their assigned weapons during daylight conditions as outlined in the previous chapters of this manual.
All procedures for the BIS are the same as with standard iron sights. Care must be taken when annotating the impact of the rounds. Related Posts

Design[ edit ] The ACOG is available in a variety of configurations from the manufacturer with different reticles , illumination, and other features. Most ACOGs do not use batteries for reticle illumination,  being designed to use internal phosphor illumination provided by the radioactive decay of tritium. The tritium illumination has a usable life of 10—15 years. Normally this allows the brightness of the reticle to match the field of view since it collects ambient light from around the sight, although this can lead to a mismatch in lighting - such as sunlight hitting the light pipe directly, or standing in a shadow - causing the reticle to be much brighter or darker than the target. The technique is essentially using the illuminated part of the reticle and its focusing rear eyepiece as a collimator sight. In this both-eyes-open technique the brain superimposes the aiming reticle on the target.

With earlier versions of the TWS, scanning too fast causes a stuttering zcog the screen, which causes axog soldier to miss or overlook a target. The more accurate the boresight of the M68 to the assigned weapon, the closer to a battlesight zero the weapon will be. The BIS is adjusted for a meter battlefield zero to provide backup in the event an optic or laser device fails to function. No centering or focusing is required. The precise boresighting of a laser will allow direct engagement of targets without a meter zero.
