周四晚上，美国军用飞机对危地马拉进行了两次驱逐飞行，与此同时，第一批地面部队抵达南部边境，这是特朗普政府动用军队帮助海关和边境保护人员的一部分。

　　白宫和五角大楼都在优先考虑有关边境任务的新闻，五角大楼在未来10天内只允许社交媒体发布有关该任务的帖子，同时在全球范围内重新调整其社交媒体任务。

　　1500名海军陆战队员中的第一个军队周四晚上，人员也开始抵达边境，圣地亚哥附近的海军陆战队抵达与墨西哥的边境墙，铺设额外的蛇腹形铁丝网，为更多部队的到来做准备。

　　同一天晚上，两架美国空军C-17飞机从亚利桑那州图森的戴维斯-蒙森空军基地和得克萨斯州埃尔帕索的比格斯陆军机场起飞，载着大约80名被驱逐者返回他们的祖国危地马拉。

　　大约1，000名美国军人，主要是来自美国各军事基地的宪兵部队，正在前往得克萨斯州的一些地方协助CBP人员，不过目前还不清楚他们将在新的任务中做些什么。

　　据一名美国官员称，这1500名士兵将不会执行执法任务，他还强调，军事人员只是被派往边境支持国土安全部，他们不会与穿越南部边境的移民有任何互动。

　　C-17驱逐飞行的第一个词来自白宫的X账户。同一天晚些时候，在圣地亚哥边境的第一段官方视频也发布在同一个账户上。

　　这些帖子表明，特朗普白宫正在优先考虑边境任务的新闻，并通过其社交媒体账户的规模接触到大量受众。

　　“正如他所承诺的那样，特朗普总统正在向世界发出一个强烈的信息:那些非法进入美国的人将面临严重后果，”白宫官方表示。

　　周五晚些时候，国防部参谋长乔·卡斯帕(Joe Kasper)发布了一份备忘录，称国防部将暂停其在全球范围内的所有社交媒体帖子10天，以重新将该部的注意力集中在特朗普的关键任务上，即“保持美国安全，部署地球上最致命的力量，以及打胜仗”。

　　但一个值得注意的例外是，关于军方在南部边境的支持任务的帖子，他称之为“重中之重”，特别是意味着未来10天国防部社交媒体帖子将是关于边境沿线的行动。

　　C-17飞机抵达危地马拉时对当地媒体开放，他们拍摄了160名被驱逐者从巨大的军用运输机上下来的视频和照片。

　　一位美国官员说，近期没有安排进一步的驱逐航班，他指出，航班的速度取决于多种因素，即国务院能够获得将接收其国民的国家的外交认可。

　　典型的情况是，DHS使用包租的民用飞机进行递解出境或遣返飞行，返回被递解出境者的祖国。

　　美国运输司令部发言人告诉美国广播公司新闻，这两次驱逐飞行是自1982年军事司令部成立以来，USTRANSCOM飞机首次用于此类任务。该司令部的历史学家无法确定国防部是否在此日期之前执行过此类任务。

　　美国国家警卫局(National Guard Bureau)周四表示，它随时准备为边境任务提供进一步援助，自2018年底第一届川普政府时期以来，已有2500名联邦化的国民警卫队成员被授权向CBP提供支持任务。

　　美国国防部官员周三表示，他们预计边境沿线可能会有额外的增兵请求。

　　“这仅仅是开始。这是第一步，我们期待着更多的任务，”一名高级国防官员告诉记者。

　　由于预计可能会被要求提供更多士兵，两名美国官员告诉美国广播公司新闻，陆军已先发制人地将第82空降师和第10山地师等高调部队置于待命状态，以备在短时间内需要他们。

　　然而，美国官员表示，目前没有近期扩大边境任务的计划，因为重点仍然是确保派往边境的1，500名士兵全面投入运作。

　　US military's mission on border moving quickly

　　U.S. military aircraft carried out two deportation flights to Guatemala on Thursday evening at about the same time that the first ground troops arrived at the southern border as part of the Trump administration's use of military troops to help Customs and Border Protection personnel.

　　Both the White House and the Pentagon are both prioritizing news about the border mission, with the Pentagon allowing only social media posts about the mission over the next 10 days while it carries out a worldwide refocus of its social media mission.

　　The first of 1,500 Marine andArmypersonnel also began arriving on the border on Thursday evening, with Marines near San Diego arriving at the border wall with Mexico to lay down additional concertina wire and prepare for the arrival of more troops.

　　That same evening, two U.S. Air Force C-17 aircraft took off from Davis-Monthan Air Force Base in Tucson, Arizona, and Biggs Army Airfield in El Paso, Texas, carrying approximately 80 deportees back to their home country of Guatemala.

　　About 1,000 U.S. Army personnel, mostly military police units, from a variety of U.S. Army bases are headed to locations in Texas to assist CBP personnel, though it remains unclear what they will be doing as part of the new mission.

　　The 1,500 troops will not be engaging in law enforcement duties, according to a U.S. official, who also stressed the military personnel are only being sent to the border in support of the Department of Homeland Security and that they will not have any interactions with migrants crossing the southern border.

　　The first word of the C-17 deportation flights came from the White House's X account. The first official video footage of the Marines at the border in San Diego was also posted on that same account later in the day.

　　The postings are an indication of how the Trump White House is prioritizing news of the border mission and is reaching a large audience through the size of its social media accounts.

　　"Just as he promised, President Trump is sending a strong message to the world: those who enter the United States illegally will face serious consequences," the official White House said.

　　Late on Friday, Joe Kasper, the Defense Department's chief of staff, issued a memo that the Defense Department was suspending all of its social media postings worldwide for 10 days to refocus the department's attention on Trump's key missions of "Keeping America Safe, fielding the most lethal force on the planet, and fighting and winning wars."

　　But a notable exception was made for posts about the military's support mission along the southern border, which he labeled "a top priority" and notably means that the only Defense Department social media posts for the next 10 days will be about operations along the border.

　　The arrival of the C-17 flights in Guatemala were open to the local press, which captured video and stills of the 160 deportees getting off the huge military transports.

　　There are no further deportation flights scheduled for the near future, said a U.S. official, who noted that the pace of the flights depends on a variety of factors -- namely the State Department being able to get diplomatic acceptance by the country that will be receiving back its nationals.

　　Typically, DHS uses contracted civilian aircraft to undertake deportation or removal flights to the deportees' home countries.

　　A spokesman for U.S. Transportation Command told ABC News that the two deportation flights were the first time that USTRANSCOM aircraft had been used for such a mission since the military command was established in 1982. The command's historian could not say with confidence whether the Defense Department may have carried out such missions prior to that date.

　　The National Guard Bureau said Thursday that it stands ready to provide further assistance to the border mission, where 2,500 federalized National Guard members have been authorized to provide a support mission to CBP since late 2018 during the first Trump administration.

　　U.S. defense officials said Wednesday that they expected there could be additional requests for troops along the border.

　　"This is just the start. This is an initial step, and we are anticipating many further missions," a senior defense official told reporters.

　　In anticipation of possibly being called upon to provide more soldiers, two U.S. officials told ABC News that the Army has preemptively placed high-profile units such as the 82nd Airborne Division and the 10th Mountain Division on standby in case they are needed on short notice.

　　However, U.S. officials said there is no current planning for a near-term expansion of the border mission as the focus remains on ensuring that the 1,500 troops being sent to the border are fully operational.
