The hidden assumption that you guys seem to be using here is that there is exactly one emergency movement component per ship.

- If just one single ship has used (or otherwise damaged) all of its EM components, the button is worse than useless. It will damage the rest of the ships and not increase the fleet speed because of the one slowpoke.

- If some ships have two or more EM components, which one gets picked?


In order to really do this, you'd have to open a big window which lists all the ships in the fleet and allows you to select which components to use as a group before hitting OK.
Preferably with some indicators for which ships are slowing down your fleet, and what the fleet speed would be if the chosen components are used.

A lot more complicated than just "Use -> Emergency movement"
