Wyoming National Guard makes history

On a cold and windy January day, members of the 2nd Battalion, 300th Field Artillery of the Wyoming Army National Guard made history by conducting the first live fire HIMARS Rapid Infiltration (HIRAIN) at Dugway Proving Grounds in Dugway, Utah, Jan. 21-22, 2021.

“For the 2-300th, it’s kind of historic for us,” said Lt. Col. Robert Lemay Lejeune, commander of the 2-300th, emphasizing the importance of this event.

HIRAIN missions have been around for a long time in the military and are a staple of combat in the Middle East that the 2-300th consistently trains for.

“This is one of our mission essential tasks,” explained Training Officer Maj. Shawn Stensaas. “It will help us improve and maintain our proficiencies and relevancy to support missions around the world, wherever they may be.”

The 2-300th first began practice for the exercise in 2015. For this attempt, they utilized a C-130 Hercules aircraft provided by the 153rd Airlift Wing out of Cheyenne, Wyo. Using the aircraft in this method allows the artillery greater mobility and a substantial increase in the overall range of their mission. This tactic makes HIRAIN missions very flexible.

“It can be used in any theatre where you can land a C-17 or a C-130,” explained Lejeune.

While it might appear that the use of aircraft in a field artillery mission like the HIRAIN would be normal, this is not the case. The normal method the soldiers of the 2-300th use to fire their artillery is to drive their M-142 High Mobility Artillery Rocket System (HIMARS) to a set point on the battlefield and then to fire from that location. While this method can be highly effective, it is limited by the range of the artillery used, usually 18-42 miles. This range can be extended by conducting a HIRAIN mission.

“I can conduct a raid but it’s as far as I can drive and secure myself forward on the battlefield,” explains Lejeune. “Which is relatively short when you compare the distance to an aircraft. So by working with the Air Force, we add this great new capability in terms of range.”

This exercise that took place Jan. 21-22 saw the 2-300th load two HIMARS and one Humvee onto the C-17 Globemaster III. The airplane then took off from Cheyenne and flew to Hill Air Force Base in northern Utah. The following day the C-17 crew flew the members of the 2-300th to Dugway Proving Grounds where the HIMAIRS exited the aircraft, obtained a good firing position, and fired their payload. They then rapidly reentered the aircraft and returned to Wyoming.

This week’s mission included collaboration from an unlikely source, the 315th OSS Airlift Wing out of Joint Base Charleston in Charleston, S.C. The 315th provided the aircraft that would was used for the event, the C-17, a much larger aircraft that allowed the 2-300th to use two of their HIMARS and one Humvee.

This collaboration with the 315th came about by happenstance according to Col. Kent M. Porter, commander of the 115th Field Artillery Brigade, which is the headquarters unit for the 2-300th.

“They reached out to me,” Porter said, explaining how the mission came to life. “They had a mission on the west coast and part of their validation is to take mobile equipment up in their aircraft. I made a few phone calls and we have just built a good relationship that we hope to have continue.”

“We cannot do this without their assistance, it truly is a team effort,” Lejeune concurred.

Given the essential status of the HIRAIN mission in combat operations, training was required to conduct these exercises safely and effectively. The teamwork between the 2-300th and the 315th should continue for a long time.

Field artillery conducts live-fire exercise

The 2-300th Field Artillery Battalion (FAB) of the 115th Fires Brigade conducted a live-fire exercise with their high mobility artillery rocket systems (HIMARS) last Tuesday. The exercise is the culmination of their annual training in which they are required to qualify with the system every year. But what many may not know is the amount of preparation that goes on before the rockets even fire.

Before firing, they must adhere to strict safety procedures. Fire Direction Officer 2nd Lt. Matthew Buchanan creates and performs the missions for the launchers and also preforms safety analysis.

“I coordinate with range control and build a safety diagram for this range, from and to our desired target,” Buchanan says. “Before the launchers can shoot, they need to verify where they are pointed to make sure they are pointed in a safe direction.”

All of this can be coordinated from a specific location. The Tactical Operations Center (TOC) is the central area where all of the preparation and communication happens. You know when the rockets are about to fire if you are standing near the area as you will start to hear excited chatter over the radios and finally, “Fire when ready!”

Soldiers are given four rockets and are required to hit a target 9,500 meters away in order to qualify. Normally there are 16 HIMARS that fire four rockets each for qualification. This time, there are only four.

This was a different type of annual training for the 2-300th as most of the Soldiers are either deployed or just coming back from deployment, so the number of Soldiers at training is much lower. Because of this, they were able to fire the rest of the rockets, 66 in total, for extra practice between the four HIMARS that were used.

“This is to ensure we are lethal and capable of doing our missions on the battlefield,” says Battalion Operations Officer Maj. Casey Henry. “They’re going through all of their certification processes to ensure that we can deploy and go to war.”

This was the first time the unit fired in this particular location. The unit continued their live-fire training and finished at the end of the week.
