A study by UK archaeologists finds that longbows caused horrific injuries similar to modern gunshot wounds.
- UK archaeologists discover medieval longbows caused injuries similar to modern gunshot wounds.
- The damage was caused by the arrows spinning clockwise.
- No longbows from medieval times survived until our times.

The Space Force will soon launch its X-37B spacecraft on a classified mission.
- The U.S. Air Force is preparing to launch its X-37B space drone made by Boeing.
- The spacecraft is like a mini-space shuttle and is used to test technologies.
- X-37B's missions are highly classified, leading to speculation about their purpose.

And the first sci-fi weapon the Space Force gets is....a device to scramble communications?
- The United States Space Force recently got its first real weapon, a satellite communications jammer.
- The device was previously used by the Air Force.
- While seemingly mundane, the jammer will serve a very real purpose on the battlefield.
I was expecting a laser of some kind, what is this?<p>The <a href="https://www.peterson.af.mil/News/Article/2071832/21st-space-wing-squadron-poised-to-receive-first-space-force-weapon-system/" target="_blank">Counter Communications System Block 10.2</a>, or CCS, is an upgrade to a previous device used by the United States Air Force for several years. The mechanism is understood to be a jammer that consists of a large trailer-mounted dish. When used, it scrambles incoming transmissions from enemy satellites. The effect is not permanent, allowing for communications to be restored after the device is turned <a href="https://www.thedrive.com/the-war-zone/32570/space-force-just-received-its-first-new-offensive-weapon" target="_blank">off</a>. </p><p>It would be used in combat operations to deny the benefits of satellite communications to enemy forces, a major factor in combat operations for any modern army. </p>
How does it work?<div class="rm-shortcode" data-media_id="d0hzsazZ" data-player_id="FvQKszTI" data-rm-shortcode-id="91415045074d263a4b3b97efbd156951"> <div id="botr_d0hzsazZ_FvQKszTI_div" class="jwplayer-media" data-jwplayer-video-src="https://content.jwplatform.com/players/d0hzsazZ-FvQKszTI.js"> <img src="https://cdn.jwplayer.com/thumbs/d0hzsazZ-1920.jpg" class="jwplayer-media-preview" /> </div> <script src="https://content.jwplatform.com/players/d0hzsazZ-FvQKszTI.js"></script> </div> <p>We don't have the exact details of how it works—however, Maj. Seth Horner <a href="https://www.peterson.af.mil/News/Article/2071832/21st-space-wing-squadron-poised-to-receive-first-space-force-weapon-system/" target="_blank">explained</a> the recent updates to it by saying, "CCS has had incremental upgrades since the early 2000's, which have incorporated new techniques, frequency bands, technology refreshes, and lessons learned from previous block upgrades. This specific upgrade includes new software capabilities to counter new adversary targets and threats."<br></p><p><a href="https://www.popularmechanics.com/military/a31703515/space-force-first-weapon/" target="_blank">Popular Mechanics</a> also found a technical <a href="https://swfound.org/media/206408/swf_global_counterspace_april2019_web.pdf" target="_blank">source </a>which speculates on the potential specifications of CCS:<br></p><p>"...it is reasonable to conclude that CCS can likely jam most of the major commercial frequencies (particularly C and Ku) and the most common military frequencies (X-band), with a possible capability in the increasingly popular Ka band. Also, it is likely that the CCS is targeted mainly at geostationary communications satellites (COMSATs), given that they are currently the primary source of satellite communications."</p>
A recent tweet shows what the jammer looks like<div id="e1c98" class="rm-shortcode" data-rm-shortcode-id="be82fc3d52bb42fdc39d7fb2eed21fb6"><blockquote class="twitter-tweet twitter-custom-tweet" data-twitter-tweet-id="1237879900867940353" data-partner="rebelmouse"><div style="margin:1em 0">SMC’s CCS B10.2 is putting the “Force” in Space Force reaching IOC, Monday, March 9th, marking the first offensive… https://t.co/zaRN9h2pKi</div> — SMC (@SMC)<a href="https://twitter.com/AF_SMC/statuses/1237879900867940353">1583968541.0</a></blockquote></div>
Why is the Space Force getting this, if the Air Force already had it?<p>While the idea of blowing up satellites with lasers or rockets seems like more fun, some considerations make a jammer more practical than the alternatives. </p><p> A kinetic weapon, like a missile, being used to blow up enemy satellites would first have to get up to where military satellites orbit, a bit higher than where other ones tend to be. While this is not an impossible task, it is a problem to solve. After it blows up the target, the issue of debris would start. Even small pieces of space junk can tear other satellites apart, imagine what collateral damage could be caused by the results of this kind of action. <br> <br> As for lasers, the kinks in laser weapons are still being worked out. There is a reason the <a href="https://en.wikipedia.org/wiki/Strategic_Defense_Initiative" target="_blank">Strategic Defense Initiative</a> never worked. </p><p>The Space Force is getting this weapon because it does exactly what the Space Force is supposed to be doing according to its <a href="https://velosteam.com/wp-content/uploads/2020/02/Space-Force-Report.pdf" target="_blank">mission</a>. This includes providing support for the other branches, when that support involves space. Stopping satellite communications to and from enemy units fits the bill. </p>
Does anybody else have this capability?<div class="rm-shortcode" data-media_id="vydnUMSy" data-player_id="FvQKszTI" data-rm-shortcode-id="3bc6ae3dc422f5acdfaef6aee5d6a08d"> <div id="botr_vydnUMSy_FvQKszTI_div" class="jwplayer-media" data-jwplayer-video-src="https://content.jwplatform.com/players/vydnUMSy-FvQKszTI.js"> <img src="https://cdn.jwplayer.com/thumbs/vydnUMSy-1920.jpg" class="jwplayer-media-preview" /> </div> <script src="https://content.jwplatform.com/players/vydnUMSy-FvQKszTI.js"></script> </div> <p>The Russians, who had an independent Space Force on two separate <a href="https://en.wikipedia.org/wiki/Russian_Space_Forces" target="_blank">occasions</a>, have a similar weapon called the "Tirada-2S" However, as is standard for Russia, details are lacking. The Chinese are also working on a similar <a href="https://www.popularmechanics.com/military/a31703515/space-force-first-weapon/" target="_blank">device</a>.</p><p>With the transfer of the CCS to the Space Force, it now takes on offensive capabilities. While it may not be as flashy as Ion Cannons, Strategic Defense Initiatives, or Death Stars, the ability to jam a communications satellite will undoubtedly prove vital in future combat operations. <br> <br></p>
Despite potential good intentions, interventionist policies are often viewed by classical liberals as violations of individual freedoms.
- Intervention covers a range of activity broader than just war. Some interventions have more humanitarian aims, such as disaster relief and development aid.
- Oftentimes, the drive behind many instances of intervention involves some form of political, economic, or social outcome.
- There are important questions to consider regarding knowledge, goals, incentives, and unintended consequences. The answers to these indicate whether an intervention is necessary and appropriate.
Proponents of drones in foreign conflicts argue that it reduces harm for civilians and U.S. military personnel alike. Here's why that might be wrong.
- There has been a huge increase in drone usage since the war on terror. Proponents of drone warfare claim it reduces civilian casualties and collateral damage, that it's cheaper than conventional warfare tactics, and that it's safer for U.S. military personnel.
- The data suggests those claims may be false, says scholar Abigail Blanco. Drones are, at best, about equivalent to conventional technologies, but in some cases may actually be worse.
- Blanco explains how skewed US government definitions don't give honest data on civilian casualties. Drone operators also suffer worse psychological repercussions following a drone strike because of factors such as the intimacy of prolonged surveillance and heat-sensing technology which lets the operator observe the heat leaving a dying body to confirm a kill.
