DOUALA, Cameroon -- Uniform top already darkened with sweat, Staff. Sgt. Joshua Crenshaw calmly halts the Cameroonian Armed Forces soldier in front of him."Stop, you're dead."It's 9 a.m. in Douala, and the humidity is pervasive. Crenshaw, an explosive ordnance disposal technician and team leader, is overseeing a practical exercise - one in which the real-life applications can mean life or death.Crenshaw is one of a handful of Soldiers from the 764th Ordnance Company (Explosive Ordnance Disposal) out of Fort Carson, Colorado, who came to Cameroon at the request of U.S Army Africa during Counter Improvised Explosive Device-Defeat Phase I training, Oct. 23 to Nov. 17, 2017, to help Cameroonian troops learn more about IEDs and how to dispose of them safely.While IEDs have long been used in conflicts, they are a favorite among terrorist organizations. Cameroonian Armed Forces regularly deploy to northern Cameroon--an area where the violent extremist organization Boko Haram operates. According to the United Nations, attacks by Boko Haram have displaced up to two million people in the countries of Cameroon, Nigeria, Chad, and Niger, and have claimed the lives of up to 15,000 people since 2009.So Crenshaw and his team, many with experience countering IEDs in Iraq and Afghanistan, are taking what U.S. EOD Soldiers learn in their nine-month course and condensing it into four-week courses -providing potentially life-saving training in the fight against violent extremism."We're here passing on the knowledge that will hopefully save these guys' lives," said Crenshaw. "It will make them slow down, make them think about it before they just run into a situation."Crenshaw explained that the students in the course come from different military departments -engineers, presidential guard, and the rapid response brigade - and have had little to no IED-specific training in the past."We're trying to help them get ahead of the game, teach them how bad it could be, and teach safe methods now," he said.During the course Soldiers of the 764th went over how to manage many IED threats that the Cameroonian troops might encounter including vehicle-borne IEDs, suicide vests, IEDs buried in the ground, weapons caches and more."This training is relevant, because of the emerging threat of IEDs," said Crenshaw. "When we start our training we usually ask what the threats are. Their leadership told us that the big threats that they're seeing are vehicle-borne IEDs and suicide vests."Crenshaw said it was rewarding to see the growth in the students from the first day to graduation."This training is essential," said Cameroonian Armed Forces Maj. Rene Didier Bekada, deputy commandant of the Cameroonian Armed Forces engineering school. "And it is really the heart of the struggle against groups who are waging asymmetric warfare [in Cameroon]."Bekada said the training increased the Cameroonian soldier's capacity."The U.S. instructors have vast experience … and so during this training we are really profiting from their experience in counter-IED," he said.1st Lt. Jacob Schall, platoon leader for the 764th, said his team is one of many partnering with militaries in other West African nations and conducting similar training."We come here and we teach them the very basics of IED defeat … hopefully they can take that expertise and take it to wherever they are deployed to and help educate their fellow soldiers," Schall said.He explained he also witnessed clear improvement in the Cameroonian troops' counter-IED skills through the training."They have a firm grasp of being as safe as possible, which is the whole point here--to increase your survivability and freedom of movement," Schall said.This is the first phase of the exercise in fiscal year 2018--the 764th team is scheduled to return to Cameroon in the spring to run two more cycles of the same exercise with new groups of Cameroonians soldiers."We're very concerned about the long-term fight that they're going to have," Crenshaw said, explaining that IED threats become more complex as extremists gain experience."It means a lot to me personally," said Crenshaw. "I've done the fight, I've done what they're going to do, and I know how dangerous it is. I've been on both sides of the effects of it, so it means everything [to me]."
