UAS Human Factors, Ethical and Moral Issues in Remote Warfare

            Unmanned aircraft systems (UASs) have always been strongly associated with warfare.  Historically, UASs have been utilized during times of war for the purposes of reconnaissance, surveillance, defense and targeting.  These UASs were designed with the intention of performing tasks that were deemed to be too risky or dangerous for standard manned aircraft.  Moreover, UASs afforded pilots the ability to complete these risky missions without necessity of placing themselves or their crew in physical danger.
 Studies have repeatedly indicated that UASs were designed to replace manned aircraft during war for tasks that were considered to be dangerous, dirty, and dull, also known as the three D’s of a consistent operational pattern (Barnhart, Shappee, & Marshall, 2011).  This was particularly an issue with manned aircraft as pilots in war were typically placed in situations where there was a significant likelihood of risk to the pilot and crew.  For example, an enemy may be targeting the manned aircraft for takedown.  A UAS could perform the same task in this situation, but reduce or eliminate risk to the pilot and crew by replacing the manned aircraft.  As a result, there are various human factors, ethical, and moral issues to consider in regards to the use of UASs in warfare.
It is this author’s opinion that UASs should continue to be used in warfare.  The primary reason for this is due to its benefits to reduce human risk.  As previously mentioned, replacing manned aircraft with unmanned aircraft in the line of fire can significantly decrease casualties of war.  Sending a UAS to complete a risky or dangerous mission can and often does result in the protection of lives that may have otherwise been lost if the task had been performed by a manned aircraft.  Further, this also helps protect against certain human factors risks. 
Pilots are susceptible to many environmental factors including fatigue, temperature, air pressure, noise and vibration stress among others.  Most, if not all, of these issues can be easily resolved by sending a UAS instead of a manned aircraft.  Since the operator is controlling the UAS remotely, they are not affected by the physical stressors (vibration, noise, etc).  However, this may present new human factors issues.  For example, although a pilot of a UAS may not suffer from the same form of fatigue as a manned aircraft pilot, this does not mean they will not suffer fatigue at all.  In fact, the task of monitoring their screen for hours on end can end up being just as fatiguing.  This is why shiftwork and necessary sleep would be critical to help eliminate the issue of fatigue.  Along with some human factors problems, the use of UASs can also present some ethical and moral dilemmas.
Currently, UASs are capable of executing lethal force; however this is something that is regulated.  This has its benefits and its drawbacks.  UASs present technological capabilities that can make targeting and eliminating enemies of war efficient and successful.  The clear benefit is that battles can be ‘won’ without needing to step foot on soil.  Instead, operators are able to carry out missions and eliminate targets remotely.  Unfortunately, this can also be viewed as a drawback as it may present some ethical issues.  For example, some may argue that removing the operator from the war field isolates them from the environment, thereby producing a sort of disconnect which may make it easier for them to take lethal action without necessarily considering morality.  In a sense, it makes warfare appear more like a video game, and less real, thereby removing some of the liability from the UAS operator.  Contrarily, manned aircraft literally immerse the pilot in the heart of the action.  In this way, it becomes much more difficult, if not impossible, for the pilot to disassociate him or herself from warfare.  When a pilot of a manned aircraft takes lethal action, it is likely to affect them more so than an remote operator of a UAS.  However, these are issues that can be mitigated with training, briefing, and debriefing.
Although this author believes that UASs remove a layer of moral boundaries, it is still this author’s opinion that UASs should continue to be used in warfare.  The countless lives that UASs can save by implementing them in war outweighs the drawbacks.  Currently, UASs can serve many purposes in war.  Not only can they be deployed to eliminate targets, but they can also serve as decoy targets as well.  This helps reduce threat to actual manned aircraft as well as soldiers and can ultimately save many lives.  However, as with any piece of technology, there is always room for improvement. 
Future considerations should carefully assess the lethality of UASs particularly with autonomous UASs.  Although lethal use is often necessary in warfare, automated lethality should be assessed with caution. If an operator of an autonomous UAS is considering using lethal force, this could cause many problems.  In military remote operations, the operator may spot a target.  The operator must then decide whether or not to engage the target based on four factors: previous knowledge/known factors, danger posed by the subject, the benefit of detaining the subject, and the probability of successfully detaining the subject (Straub, 2013).  When operating UAS, a human being is responsible for making these judgment calls.  However, autonomous UASs have the capability of making this decision without human input.  Due to the high-risk nature of warfare, this author suggests that it is preferable to have a human making lethal decisions rather than an autonomous UAS.
Conclusively, although UASs should continue to be used in warfare, automated lethality should not be used as a person should always be in the loop for moral considerations.
