To be honest, after entering interstellar warfare, attack methods like this had become quite rare. The reason is simple: nowadays, the weapons are all for ultra-long-range combat, whether they are energy weapons or conventional firearms, their power is enormous. However, when it comes to being effective against the Cloud Spirits, that's quite challenging. Not to mention, just the layer of energy shield on the Cloud Spirits themselves makes it difficult for long-range weapons to destroy it.
Of course, it's not absolutely impossible, but if the battle is fought at long range, the Cloud Spirits are not without means. And when it comes to a certain proximity, that is when the Sanctuary soldiers strike. In short, the existence of these Sanctuary soldiers is not without purpose.
