We were basically given a crash course on the capabilities of an Exo-Knight in that one lesson.
So what I learned was that Exo-Knights were originally designed to be heavy armour units that can be dropped from orbit during the war with The Confederation.
They worked as both artillery platforms and titan units that would help breach fortified positions and initiate surprise attacks on enemy forces.
Someone then had the great idea to make them spaceworthy by putting thrusters on them and they became an all rounder that can be deployed both as a planetary landing force and an orbital fighting force.
They were basically seen as the jack of all trades since you could just use Exo-Knights to clear out a planet's orbital defenses with them before moving on to a planetary assault without needing other specialised ships.
Well… Theoretically anyway… Since no one attempted such a thing as it's always better to have support ships during a battle.
