本周，美军结束了其参与的年度北极训练演习，此次演习首次同时在阿拉斯加和格陵兰岛举行。始于2018年的”北极边缘”演习（Arctic Edge）包括应对俄罗斯——以及日益增长的中国——可能对美国构成威胁的训练内容。
格陵兰岛部分由丹麦协调组织，涉及美国和丹麦特种部队。尽管今年特朗普总统多次威胁要控制格陵兰岛（丹麦的自治领土），但这次长期计划的演习仍如期举行。
负责此次演习的北美防空司令部（NORAD）和美国北方司令部表示，丹麦在格陵兰岛接待了美军，重点训练北极环境下的作战能力。”北极边缘”演习每两年在冬季举行一次，今年是近年来首次在深冬时节开展。

北美防空司令部副司令、加拿大皇家空军中将伊恩·哈德斯通（Iain Huddleston）本周早些时候对记者表示：”在北极冬季演习中，一半的战斗是单纯的生存挑战。”
美国阿拉斯加司令部、阿拉斯加北美防空防区司令兼第11航空队指挥官罗伯特·戴维斯少将（Robert Davis）表示，此次演习的总体教训是，军队必须在抵达北极前就做好准备。
戴维斯指出，在训练中，由于缺乏对极寒地区独特操作方法的熟悉，常规会出现飞机受损并需要额外维护的情况，例如未提前预热液压系统。一些士兵会过早打开飞机窗户，导致窗户破裂。
“现在你必须更换窗户才能继续使用飞机——这些只是不经常在极地操作突然转换到北极环境时，不得不进行’探索性学习’所面临的一些实际挑战的例子，”戴维斯说。
哈德斯通和戴维斯表示，此次演习没有设置理论上的对手，但包含防御特定武器的部分，如只有俄罗斯和中国等特定国家可能用来威胁美国的巡航导弹。
“我们没有任何情报表明我们确实面临来自俄罗斯或中国的巡航导弹袭击阿拉斯加的风险，”戴维斯说，”然而，我们认为有必要充分准备，利用美国政府赋予我们的军事能力，从防御角度确保这些能力能够协同运作。”
军事日益关注的小型武器是无人机。在演习中，美军在阿拉斯加的格雷利堡（Fort Greely）演练了应对无人机入侵的场景。
戴维斯称，他们测试了包括单一无人机可能只是监视基地以及约六架小型无人机群在内的多种情景，以验证格雷利堡现有的不同系统是否能够探测到无人机并向陆军士兵传递信息。
“没有一架无人机完全未被探测到，”戴维斯补充道，”有多种类型的传感器，至少有一种传感器探测到了每架无人机，且所有系统均未受到温度骤降至华氏零下40度的负面影响。”
戴维斯表示，美军确实击落了一架无人机，但使用了一种反无人机系统，该系统向无人机投掷网罩并将其完整地降落在地面，以便美国检查。
由于格雷利堡的反无人机系统主要基于电子设备，不一定需要电池（电池在寒冷中会迅速耗尽），因此温度”并没有对其产生负面影响，这很好，”戴维斯说。
他指出，工业和商业公司修改和改进无人机技术的速度之快，使得军队内部的正式项目”很难”跟上。这是五角大楼在整个武装部队中面临的问题，而不仅仅是在北极地区。
Military exercises in Alaska and Greenland test forces on operating in Arctic conditions

U.S. forces this week wrapped up their participation in an annual Arctic training exercise that for the first time was held in both Alaska and Greenland. Arctic Edge, which began in 2018, includes training to respond to threats that Russia — and increasingly China — could pose to the U.S.
The portion in Greenland was coordinated with Denmark and involved both U.S. and Danish special forces. The long-planned exercise took place despite President Trump’s repeated threats this year to take control of Greenland, which is an autonomous territory of Denmark.
According to NORAD and U.S. Northern Command, which ran the exercise, Denmark hosted the U.S. in Greenland for training focused on operating in the Arctic. Every other year, Arctic Edge takes place in the winter and this year’s was the first in recent years to take place in the dead of winter.

“Half of the battle in exercising in the wintertime in the Arctic is simply surviving,” Royal Canadian Air Force Lt. Gen. Iain Huddleston, the deputy commander of NORAD, told reporters earlier this week.
The overall lesson of the exercise is the military must prepare units for the Arctic before they get there, according to U.S. Air Force Lt. Gen. Robert Davis, who is the head of U.S. Alaska Command, the Alaskan NORAD region, and commander of the 11th Air Force.
During the training exercise, according to Davis, there are routinely aircraft that are damaged and require additional maintenance because of the lack of familiarity with practices unique to the extreme cold, like warming up hydraulic systems beforehand. Some service members try to open the window on an aircraft too soon, and the window cracks.
“Now you can’t use the aircraft until you replace the window — so, a couple of examples of just some of the practical challenges of not operating on a routine basis, and then all of a sudden coming up into the Arctic and having to do a little discovery learning,” Davis said.

Huddleston and Davis said the exercise did not have a theoretical adversary but had portions to defend against weapons, like the cruise missiles that only certain countries, like Russia and China, could potentially use to threaten the U.S.
“We don’t have any intelligence that would suggest that we’re actually at risk of them launching cruise missiles against Alaska,” Davis said. “Nevertheless, we feel like we need to be adequately prepared to take the military capabilities that the U.S. government has given to us from a defensive perspective and make sure that we can put them together.”
A smaller weapon of increasing concern to the military is the drone. In the exercise, the military practiced responding to a drone incursion at Fort Greely in Alaska.
According to Davis, they tested scenarios including a single drone that might just be surveilling the installation as well as a small swarm of about six drones, to see if the different systems Fort Greely has were able to detect and communicate information to the Army soldiers.
“None of the drones were completely undetected,” Davis said, adding that there are multiple types of sensors and at least one of them detected each of the drone, and none of the systems were negatively impacted by the temperature, which can plummet to -40 degrees fahrenheit.
The U.S. forces did take down one drone, according to Davis, but used a counter-unmanned aerial system that throws a net over the drone and lowers it to the ground intact so the U.S can inspect it.
Because the counter-drone systems at Fort Greely are mostly electronics based and don’t necessarily require batteries, which can drain quickly in the cold, the temperatures “didn’t really affect them in a negative way, which is good,” Davis said.
He said the speed at which industry and commercial companies are modifying and changing drone technology makes it “really difficult” for the formal programs within the military to keep up. That’s a concern the Pentagon is confronting throughout the armed forces, not just in the Arctic.
