How to limit the display of tanks and battles

The lists of battles and tanks can be filtered for various purposes. You might want to look at all tanks of a specific tier, all battles of one tank, all battles within a certain period of time, etc.

The filtering options appear as context menus for both tanks and battles:

Multiple selections across the filtering menus can be made. Clicking a second time removes the selected element from the filter.

By right-clicking a battle in the grid, you can filter on battles fought with this tank.
