CheatCommands Mod - an utility mod for Company of Heroes 2 featuring large set of tools.
This upcoming feature allows you to set game camera to follow the last entity in the world. For example using ability which calls in an airplane creates a new entity for the airplane and thus it will be last one in the entity list.
This feature will be available in version 1.23 alongside with several other new implementations.
In the posted video you can see how you can manipulate the camera while following the airplane. This is just a rough example.
