Tanks and large ships have become obsolete.
There are two types of ships. Submarines and targets.
No the older ones have. The systems that we have been observing getting destroyed are near the end of or even past their service life. W have many things here in the US arsenal that can have the same thing happen to them.
No they haven’t. Both tanks and capital ships have their purpose and place in the modern battlefield.
But they aren’t placed by themselves.
Look at American aircraft carrier groups. These not only have an aircraft carrier but destroyers, frigates, aircraft and submarines. It can take on anything.
Russia has just proven that bad planning and organization can kill the invader.
The Ukraine War is illustrating that.
