Not every mech force could support the logistical burden of maintaining a large amount of modularized mechs.
In theory, it all sounded pretty good. By developing a modular mech such as the Bright Warrior Mark II that could equip all kinds of optional modules and equipment, the mech pilots could reach their full potential by piloting the configurations that precisely matched their unique skills and inclinations.
A school of military theorists even proclaimed that personalization at the company, squad or individual level was the future of mech warfare!
After all, why should every mech pilot be stuffed into a standard mech that had never been designed for that person in the first place?
While it was way too extravagant for mech designers such as Gloriana to design bespoke mechs for thousands of rank-and-file mech pilots, the development of a modular mech provided an excellent compromise solution!
