It&#x27;s mostly a propaganda things, but in special operations (from were many things in the military gets appropriated) it has a purpose. Which isn&#x27;t about &quot;comfort&quot; as some has suggested, but rather about accountability. If you don&#x27;t speak up about something and someone gets in trouble, you will have to go and get them. Which works both ways. But also if you make a mess, your friends will have to risk their lives (more than usual) to come get you and that is a horrible rather than comforting thought.<p>It&#x27;s basically &quot;we are all in the same boat&quot;, which is true (sometimes literally) when you&#x27;re engaged in high-risk activities. Note that high-risk in this case doesn&#x27;t mean that you might get killed, but that there is a low margin for error leading to catastrophic failure. Special operations are not about being a fair fight, it&#x27;s about using your advantage and once you loose that you&#x27;re often in big trouble.<p>Say you&#x27;re doing recon on enemy territory and calling in airstrikes. You&#x27;re a small mobile force that is hard to find having disproportionate impact on the battle, which is good. Then someone drop a glove or breaks his leg or anything else that compromises the mission and now you&#x27;re just a small force soon to be a disproportionate loss, which is bad.
