In a near-future situation where the manpower pool of conventional mechs got dwarfed by the manpower pool of Carmine mechs, mech battles would never become the same again.
At least red humanity became too consumed by the Red War to even think about employing Carmine mechs against their fellow man.
Original humanity did not have any particularly threatening external enemies at this moment.
The people of the Milky Way would most certainly turn their shiny new Carmine mechs against each other!
This meant that the adoption rate and development of brand new mech doctrines centered around their usage would accelerate very quickly.
Those that understood the advantages of Carmine mechs faster than others would definitely invent pioneering new strategies and approaches towards warfare.
Carmine mechs would definitely be deployed in far greater numbers than ordinary machines.
