Designated Marksmen Semi Automatic Rifle & Sniper Bolt Action Rifle Shooting Requirements

Long range precision shooting involves some specialized equipment as well as techniques. Breath control is one. It has been documented that the most proficient snipers can consistently shoot between heartbeats. There are differences between snipers but probably not as much, though there are some vary talented marksman in the sniper ranks, as with anything there a few that are at the top of their game and excel in execution of their profession. But the training regimen tends to bring all who pass the ridged training program to a degree of proficiency that levels the playing field. Snipers operate alone or in small teams with independent mission objectives.

Objectives & Requirements of Snipers & Designated Marksmen

Many designated marksman (DM) are chosen because they are the best shots in the squad or platoon. Therefore, the capabilities between DM’s may vary. DMs receive additional marksmanship training but operate with the organic unit either at the squad level (SDM) or platoon level (DM). They usually operate by without an observer/spotter, unless the unit leader decides that tactics require a two-man team. The mission is in direct support of the unit to provide efficient direct fire supporting the unit’s mission. But there is no denying the fact that snipers and DMs have some very nice ‘toys’ that aid them in their pursuit. Snipers provide precision fire, on a specific target. They serve to curtail maneuver thus restricting movement and contribute to a decline in enemy morale.

Designated Marksman VS Sniper Rifles

• When the Vietnam war opened up the Marine sniper were using M1903A4 Springfield of WWI and WWII fame. These served in Korea and were chambered for the .30-06 cartridge. The Marine Corps was using some Model 70 Winchester bolt actions as well.
• The Army went the semi-auto route in 1966 and adopted the M14 in 7.62 NATO, the mounted the Leatherwood this resulted in the auto-ranging telescope or ART. As the zoom ring was turned a cam would adjust for range and was combined with Redfield Accu-range 3-9 variable a commercial offering. These were built by the US Army Marksmanship Training Unit (USAMTU) and when completed shot 10” groups at 900 yards. These were designated M21. The advantage of the semi-auto sniper rifle is that they can better provide defensive fire if the enemy attempts to overrun the snipers position.
• The Marine Corps adopted the M40 built on the 700 Remington bolt action in 7.62 NATO. These had the short action for 7.62 cartridges. The long action could accommodate the 300 Winchester Magnum, an option adopted by the Army when they acquired some M40. That way they could re-barrel if the more powerful platform was needed. The Army version was the M24 with the long receivers. Today the M24 alternate chambering is the .338 Lapua Magnum. The Army has recent issued this weapon in 300 Winchester Magnum with special match ammo good for out to 1,500 yards.
• The US forces also utilized the Barret family of heavy rifles for vehicle and material destruction plus anti-personnel interdiction. These are chambered in 50 BMG or 12.7 x 99mm Browning heavy machinegun cartridge. Some Barret’s are also shooting the 338 Lapua Magnum.
• Our northern neighbors have adopted the C14 Timberwolf in .338 Magnum good to 1,500 yards.
• The Canadians and US Seals use the McMillan TAC-50, it’s a bolt action with a 5 round detachable magazine.
