Is the Shock Infantry tag used for anything?
The Eagle Runner Knight is the only unit that I can think of that has that tag without having the Hand Shock Infantry tag.
Maybe this tag should be completely removed from the game and for those few cases where something is applied to Hand Shock Infantry* and Eagle Runner Knights they should just be added manually.
Maybe the Eagle Runner Knight tag should not be hidden in general. It might be a useful tag for future units.
This unit is the most confusingly tagged unit in the game despite being a simple Light Cavalry unit is practice.
