Idaho Army National Guard fires precision-guided munitions

BOISE, Idaho – The Idaho Army National Guard’s 1st of the 148th Field Artillery Regiment conducted its first live-fire training and certification using the Army’s modernized M1156 Precision Guidance Kit during the battalion’s annual training in the Orchard Combat Training Center May 12-27.

“The Idaho Army National Guard continues to receive and train on some of the military’s most modernized equipment so we can remain relevant and ready to defend our nation’s interest anywhere in the world,” said Brig. Gen. Farin Schwartz, commander of the Idaho Army National Guard. “The Idaho Army National Guard is one of the most modernized states in the Army National Guard, with equipment that enhances our capability to be interoperable with our active-duty peers.”

The modernized GPS guidance kit with fuze functions and integrated GPS receiver weighs 3 pounds and attaches to existing 155 mm artillery shells, converting them to smart weapons for improved target trajectory. Small aerodynamic fins on the fuze allow the system to make flight adjustments of the round’s trajectory and steer the shell on target.

This enables the 1-148th FAR to deploy munitions within 30 meters of a target instead of the average 50 meters of traditional artillery, increasing the battalion’s lethality and decreasing costs, said Lt. Col. Brady Johnson, commander of the 1-148th FAR.

“Being PGK certified greatly increases the lethality of the field artillery battalion,” said Johnson. “The modernized weaponry allows 18 separate targets to be simultaneously targeted and attacked at a third the cost of conventional missions with minimal clearance of fire issues.”

Traditionally, the battalion would attack three enemy targets with a battery-sized element and six M109A6 Paladins, each firing three rounds of ammunition for a total of 18 rounds. Johnson said it costs about $20,000 for 18 rounds of conventional 155 mm ammunition, which may or may not hit an intended target, whereas the more accurate PGK costs $6,500 per kit.

A fail-safe can also prevent the shell from exploding if it falls outside 150 meters of an intended target, enabling Soldiers to call in artillery support close to their position more confidently and reduce collateral damage, said Sgt. 1st Class Mike Taylor, 1-148th FAR master gunner.

Soldiers first trained on the PGK when the battalion traveled to Camp Guernsey, Wyoming, for annual training in July. But they were unable to conduct live fire with the precision-guided munitions. Soldiers again trained on the PGK’s capabilities before conducting several live-fire missions, first with conventional rounds and then with the PGKs.

More than 80 rounds were fired, including more than 50 PGKs, helping ensure the battalion’s ability to successfully perform its warfighting mission and certify using the modernized precision-guided munitions.

“With the new technological advancements of today, it’s vital for us to be modernized,” said Taylor. “The 1-148th is really good at what we do, but with the new PGK, we are even better, hitting targets with every single round. This type of weaponry is going to be crucial on the current battlefield.”

The 1-148th FAR employs fire to destroy, neutralize, suppress or shape enemy forces; provides fire support to maneuver in close combat and during counterattack to control land areas; and provides counterfire.

It is equipped with the M109A6 Paladins that fire 155 mm artillery shells. Crews that operate the Paladin consist of a driver, a No. 1 man, a gunner and a section chief.

The No. 1 man is responsible for loading and firing the weapon. The gunner fuzes the round and cuts propellant powder, while the section chief manages all firing data and ensures the weapon is laid on target.
