Different people may have different perceptions and experiences regarding schizophrenia. They may have hallucinations, they may have delusions, they may have disorganized thoughts and/or speech, and they may have a group of different symptoms. Whilst there are clear, theoretical definitions of what schizophrenia is, different people do experience it differently. For example, some people may believe that they are the chosen one, something like a savior, like Leo in Matrix. So they can survive anything, no one can kill them, an the European Eastern Front, one of the deadliest and the most brutal battlefield in the history of human warfare, is a piece a cake for them. For another instance, as I have said, I believe in the fact that telepathy exists, so the Germans could easily find me, arrest me, and treat me to their friendly gas room for shower. Whether you will actually survive is based on your specific situation and circumstances, and your ability to make reasonable plans and decisions, and, of course, based on luck. Different people have individual thoughts and opinions, but I still insist that people with schizophrenia are disadvantaged in warfare.
You have made a good point regarding the Scandinavians. That said, I still insist that, although bravery and fearlessness are very crucial in warfare, it is equally important to be able to think critically and make reasonable, logical decisions. At the individual level, just at the front, and under a pre-modern setting, bravery is important. However, as you go up in the rank and become some kind of an officer or commander, the importance of having a clear, reasonable mind increases. On the other hand, there were a lot of sober people without any mental illness who could behave in a very brave, fearless manner. If you have seen the film “Enemy at the Gates,” you knew that, at the Eastern Front, the Russians sometimes forced their conscripts to rush towards the German line of defense, and they had some commissars and designated people to “supervise” the assault of the conscripts. If the conscripts dared to run back, they used a machine gun to massacre them. For another example, the Empire of Japan used to brainwash their soldiers into showing absolute loyalty to their Emperor. The Japanese soldiers could run towards you, in their hands there was a rifle with a pointy bayonet at the edge of it. Those soldiers did not have schizophrenia, but they behaved like crazy maniacs. The monsters behaved like this when they massively invaded my country, and also in the Pacific, when your country had to deal with them. If you want to observe them, you can have a try on the video game Call of Duty. Nevertheless, I’m still not fully convinced that being “brave” and “fearless” would increase your likelihood of surviving the Eastern Front, as I personally believe that those “insane” behaviours, like holding a knife and running towards your enemy, are not the best way to fight a war. This is the exact reason that I think critical thinking with reason and logic is also very important.
Yes, if you live in Ukraine or Palestine, then the war is directly related to you, it’s a matter of life or death, just like in the game This War of Mine. You indeed need to defend your country, but it also doesn’t mean that everyone should be enlisted. You can serve in the military as a soldier, or you can also contribute to the defense of your country as a civilian. In fact, if you forcibly enlist someone who is not suitable for serving in the military, then it may backfire and harm your national interests. People with schizophrenia cannot control their psychosis or episodes, their illness is passive, not like an ability or a gift. What if, when facing severe pressure, they develop mania, and commit friendly fire? This is why every mature country does have a rigorous standard for enlistment.
I indeed don’t know much about how things are done in the United States of America, at least from a military perspective. The US is a modern, developed superpower, isn’t it? Maybe you once served in the US Army, and they did things in that way. But, is it many years ago or not? I guess they may have changed their practice, in accordance to the demands of modern warfare, is that correct?
In my country, the requirements for enlistment are very rigorous. They have requirements on height and weight, and people with schizophrenia tend to be overweight, due to the anti-psychotic medications, so I’m out. They also have requirements on eye-sight, both eyes. I have poor eye-sights and wear a pair of glasses, so I’m also not eligible. What’s more, it’s written in black and white that people with some certain mental illnesses cannot enlist, including schizophrenia, depression, mania, etc. So I’m completely out. I do have two arms, I am able to drink alcohol, and I can walk backwards for a little bit, but there’s no way I can be even an infantry in my country, let alone pilot for a fighter’s jet. The military service is voluntary in my country, but I cannot join the military, no matter whether I want to or not.
On a side note, there are checks on things unrelated to health as well. If you have tattoo, and your uniform cannot cover it to a certain extent when you wear your uniform, then you’re out. Also, there are some special requirements if you want to serve in some special units, like you want to be a parachuter, or you want to serve in the special forces or on a submarine.
Of course, different countries have different laws and policies, and nothing is universal. The idea is that a mature army should only allow people who meet the requirements to join them, and leave out the people who are just unsuitable or fail to comply with the requirements.
