    Training foreign troops will be the ‘flagship’ of Canada's new UN peace strategy, top soldier says

    Gen. Jonathan Vance said that despite speculation, there was never a plan in the works to deploy troops on a single UN operation. OTTAWA—Training foreign troops will be the “flagship” of Canada's newly announced peace operations strategy, says the country's top soldier, who concedes that elements of the plan still require months more work. Prime Minster Justin Trudeau on Wednesday took the wraps off his government's long-awaited effort to reengage with United Nations peace missions. Elements of the strategy include $15 million in funding to boost participation by women soldiers in UN operations; an initiative to end the recruitment of child soldiers; and the promise of Canadian personnel to assist with training. It also pledges up to six helicopters, two transport aircraft and a quick reaction force of up to 200 personnel to support UN missions. But apart from Trudeau's promise of a single transport aircraft for UN operations based in Uganda, the plan offered no details on possible deployments. Gen. Jonathan Vance, the chief of defence staff, said it would be “inappropriate” to say when those might start. “I'm not even going to hazard a guess on that one right now. Step number one is now to get into detailed planning with the UN and find out . . . the what, the where and the when,” he said in an interview. This week's announcement was months in the making. The Liberals pledged in the 2015 election to “recommit” to UN peace operations, in part by providing specialized capabilities such as medical teams and engineering support. That promise was followed in August, 2016 by a commitment to deploy up to 600 troops and 150 police officers on UN operations. Canada's contributions to UN peace missions are at their lowest levels in years with just 23 military personnel currently assigned to such operations. That's not likely to change soon. In the wake of Wednesday's commitments, Vance made clear that it will take many months yet of planning and discussions with the United Nations to determine how Canada's offers of personnel and equipment can best fit with ongoing missions. “Some of the ‘when' on smart pledges is years away. Some of the ‘when' on other potential operations is sooner than that,” he said. Some observers criticized the Liberal government for not committing personnel to a single mission, choosing instead to disperse personnel among many possible locations. But Vance said that despite speculation, there was never a plan in the works to deploy troops on a single UN operation, saying, “I've never received guidance that said do a mission with 600 (troops).” Suggestions that troops were headed to Mali, for example, or that the announcement had been delayed “didn't match the reality of the work we were doing,” Vance said. “There were a lot of assumptions made about, ‘hey, we're going to Africa',” Vance said Instead, he said that Canada was working with the United Nations “to figure out a new way of doing business.” And he said repeated fact-finding trips by bureaucrats and politicians, including visits to African countries, were not about scouting any one particular mission. “That's us doing research . . . that allowed us to arrive at an approach that government could consider,' he said. “We've been working for over a year to determine what are the various options available to government in terms of how to improve UN performance overall with Canadian troops,” Vance said. Yet given that Africa is the location of many UN missions so “it's very likely a place where we would offer contributions,” Vance said. The peace support strategy calls for a new training and advisory team to work with a nation before and during a deployment to improve their own ability to conduct peace operations. It also says that Canada will contribute to training centres and schools. Vance said such activities will be the “flagship” of the plan. “We're going to try and leverage the Canadian expertise, one of the best trained militaries in the world and best equipped, . . . so that UN mission performance can improve,” Vance said. Defence analyst Dave Perry said elements of the peacekeeping strategy make sense. The problem, he said, is that the government itself had raised expectations with its drawn-out decision-making and rhetoric about its intentions. “It wasn't just what the government was saying publicly. I think there were also a number of commitments that were strongly intimated to some of Canada's key allies,” Perry said in an interview. “My sense is that the different options that were put forward by the department of national defence for whatever reasons weren't palatable to the government,” said Perry, a senior analyst with the Canadian Global Affairs Institute. While he said the contributions to UN operations were “modest,” Perry said Canada is better off providing military support to other missions, such as coalition efforts to combat Daesh, or NATO roles. “Bluntly, there are better ways of achieving Canadian national objectives in the world that through UN missions,” Perry said. https://www.thestar.com/news/canada/2017/11/16/training-foreign-troops-will-be-the-flagship-of-canadas-new-un-peace-strategy-top-soldier-says.html

  • Okinawan Exercise Offers Glimpse Into Future USAF Air War Strategy

    Okinawan Exercise Offers Glimpse Into Future USAF Air War Strategy

    Steve Trimble The technological details of the U.S. Air Force's new approach to fighting an air war in the next decade are still being fine-tuned in laboratory experiments and simulation centers, but a few of the dramatic changes are already visible here at Kadena AB on the rocky shores of Okinawa, Japan. A local exercise held in January called WestPac Rumrunner appeared to be built around a routine counter-air scenario: Twenty-four Boeing F-15Cs scrambled from Kadena AB to a point about 100 mi. east of the island to intercept “invading” U.S. Navy Boeing F/A-18E/Fs launched from MCAS Iwakuni on Japan's mainland. Meanwhile, Special Operations Forces (SOF) aircraft attempted to infiltrate a team of commandos on the island. Underlying that routine setup, however, was a glimpse of the future. Four Kadena-based F-15Cs refueled and rearmed during the exercise at MCAS Futenma on Okinawa. Another mainland Japan-based Navy E-2D, which supported Kadena's F-15Cs against the invading F/A-18E/Fs and SOF teams, refueled at Kadena. Although those seem like trivial logistical details, both offered a chance to test the Air Force's new Agile Combat Employment (ACE) strategy. Moreover, the Navy's Northrop Grumman E-2Ds and local MIM-104 Army Patriot batteries added layers to the defenders' battle-management tasks. WestPac Rumrunner was not the full realization of ACE or Joint All-Domain Command and Control (JADC2), but the event was a tiny step on a pivotal base within the first island chain east of China. “We're trying to use all of our exercises to learn something about Agile Combat Employment and base defense,” Gen. Charles Brown, Jr., commander of Pacific Air Forces (PACAF), told Aviation Week in February. Brown has directed PACAF-controlled wings to start experimenting with two concepts that require a change in mindset as much as technology. “I don't think we've got all the answers yet, but [such events provide] feedback or validate some things we've tried to do,” Brown says. “And then we ask, ‘How do you put that into our doctrine and change our approach?'” Adapting base defenses and logistics lines across the sprawling PACAF region is a major focus for the Air Force. In February, Air Force leaders rolled out a budget proposal that includes a new logistics-under-attack initiative. The goal is to make bases more resilient to coordinated attacks aimed at weakening or destroying the hubs currently used to rearm and refuel combat aircraft. “The key aspect of ACE is to be light, lean and agile,” Brown says. “So your logistics do not become something that's a challenge.” Most of the details of the new initiative are classified, but Air Force leaders have acknowledged the plan involves dispersing forces to remote airstrips and building up base defenses. Brown also favors distributing nascent technologies such as directed-energy weapons, to serve as point defenses, lest the Air Force face the cost of deploying sophisticated kinetic systems, such as Terminal High-Altitude Area Defense (THAAD) or Patriot batteries to the dispersal sites around the region. Brown, who has been selected to become the next chief of staff, also has said he is interested in examining novel power sources such as a future class of small, modular nuclear fission reactors to serve as the generators for such high-power systems. Part of the logistics initiative has already been set in motion. PACAF eventually wants to preposition weapon systems in cargo containers around the region, but that first requires host nation approval. In the meantime, the command is laying the groundwork with proposals to preposition humanitarian relief supplies. “It really started out with [humanitarian assistance and disaster relief] capabilities that you can put in different locations,” Brown says. “If you look at this region, it's full of typhoons, volcanoes, earthquakes. And we respond to a lot of those. That, to me, is a way to start the process.” The focus on lightness and agility also marks a change. One way to reduce threats to the logistics systems is to reduce the tonnage required to support an operation, thus decreasing the overall demand for airlift. That emphasis could lead to design requirements for lighter and more efficient weapon systems, but the focus now is on paring down logistics needs to essentials and using software applications to drive new decisions about what that means. “This is where I think we start talking about data and being able to understand that better so we can forecast better,” Brown says. “And we're not bringing everything just in case—you actually bring what you need.” Finally, protecting the mobility fleet that delivers the equipment to dispersed and remote bases is another priority. Air Mobility Command, for example, has funded defensive upgrades for the Boeing KC-135 and Lockheed C-130H fleets, providing those previously undefended aircraft with warning systems and countermeasures against infrared- and radio-frequency-guided missiles. Another way to defend the mobility fleet is to make it harder for an adversary to guess where such aircraft will take off and land. “I can put [defensive aids] on a single airplane, and that's important, but I also want to look at the places we're operating from,” he says. “This is why we were looking at Agile Combat Employment. So instead of dispersing on an airfield, we disperse [combat aircraft] across airfields. And then I've got to defend that.” In addition to being costly weapon systems, THAAD and Patriot batteries also require significant airlift support to relocate and sustain, Brown says. “I'm looking for things that are lighter, leaner, where you have a more unlimited magazine, and the cost curve is different, so you can reserve your very expensive interceptor against a ballistic or cruise missile or hypersonic missile. At some point, though, you can't afford it. So having a high-power microwave and directed energy gives us a lot more flexibility to go to different locations. That's the thought process. I think there's good dialog about it. We still have a ways to go.” The first steps are taking place in local exercises, such as WestPac Rumrunner. The Kadena-based 18th Wing scored the counter-air element of the event as a success. No Carrier Air Wing Five F/A-18E/F “invaders” infiltrated the 100-mi. boundary zone circling the island. An SOF team successfully landed an insertion team, but the 44th Fighter Sqdn.'s F-15Cs immediately “killed” the infiltration aircraft, says Lt. Col. Ryan Corrigan, commander of the 44th Fighter Sqdn. The event's focus on practicing the ACE concept added another layer of complexity. Dispersed operations are not new to the Okinawan F-15Cs. A decade ago, Kadena's squadrons helped pioneer a concept called Agile Eagle, which paired enough airlifters and tankers to move a group of F-15Cs anywhere in the region at a moment's notice. The idea further evolved into the Rapid Raptor concept, which applied a similar operational model to F-22s based at Hickam AFB in Hawaii, and then into the wider ACE strategy, but it still presents a challenge to the hub-based mindset of PACAF units. Widely dispersed high-energy lasers defending bases from saturation missile attacks still seem years into the future, although field experiments with counter-unmanned aircraft systems designed by Raytheon and the Air Force Research Laboratory have begun. In the meantime, the focus on the unit level is about making practical changes. “What we can take care of now is training to not be an easy target,” Corrigan says. “It is finding the right level of acceptable risk to right-size the support package that goes with that deployment team. So [for example], now I don't need to bring both a weapons loader and a refuel team because I have trained my weapons loader to know how to put gas in several different types of aircraft.” https://aviationweek.com/defense-space/missile-defense-weapons/okinawan-exercise-offers-glimpse-future-usaf-air-war-strategy
