In unrestricted submarine warfare submarines will indiscriminately attack merchant ships regardless of which country they originate from. The goal of this type of warfare is to deny the supply of war materials to the country that you are at war with. This is a very controversial type of warfare since you attack the merchant vessels of neutral countries.
I think that when a Navy resorts to this it is in a desperate situation. This type of warfare often backfires because it can cause a neutral country to become a foe. You may ask what does this post have to do with creating a custom Navy ring, and the answer is that it has absolutely nothing but I just enjoy bringing tidbits of knowledge about just about everything military.
I don’t know how much of this type of warfare will be used in the future, especially with submarines. Modern technology is so advanced that submarines are not necessarily needed for this type of mission. I guess everything goes in love and war. I can’t justify or condemn this type of warfare but I am not particularily fond of the concept.
