I think the soldier who does that is a little ghey, but that's jsut my opinion..
And I think the carriers should be marked by some kind of bearings, a little cirkle with the time of the last bearing next to it, with a pencil! (important! if there's a bearing or a note on a map, you should use pencil, cause you can )
It looks a little unprofessional (when someone uses a stift-marker especially when it's pink!)
Coz' in real life, a ship is not a static.. they move, so they will be marked with a cirkle, in theoretic-thinking, it can move in every direction on the water.. If you want to mark another ship than yours, you will make a cirkle or an arrow large of this with the speed that he has done before this has taken off.. (with a lot of math which you will learn when you study for maritime officer
When it's your own ship, you will set just a dot.
I will make an example;

and the water,.. it's all the same depth now..
Can you also make it sea-mappishlike ?

Looks more and more realylistic than..
You guys made some good work, but it can be even better.
