While serving the Mercenary trade, the revised,
Republic-lead MRBC had also served to weaken the power and influence that the
mercenaries held. This, combined with the shrinking size of commands (the
multi-regiment commands of the pre-Jihad era being all but extinct) and more
commands becoming inactive then new ones registering, had lead to a winnowing
of the mercenary trade itself. By 3130, the mercenary trade was at its weakest
ebb since the Third Succession war, an objective that the Republic of the Sphere
had deliberately worked towards.
The Periphery powers had gotten around their lack of
representation by using Herotitus as their main hiring hall. While not
controlled by the MRBC, the generally poor quality of the units based there, as
well as the limited technology and economies of the Periphery, served as a
brake on those commands. The result was again a weakening of their influence,
as well as limiting their capabilities. The sole exception to this was the
Magestry of Canopus, who would often use the Capellan Confederation as a
go-between for hiring units.
Grey Monday and its aftermath, however, destroyed this new
stability a number of ways. Almost overnight, innumerable new commands sprang
up out of nowhere, registering with the MRBC. While many of these units were
dubious at best, often made up of converted InsustrialMechs or infantry, their
numbers swelled the depleted ranks of MRBC. Many existing commands also
expanded as a response to the growing chaos and uncertainty within the
Republic. The rate at which this happened was dramatic; in 3132, many Mercenary
Commands boasted a single lance of BattleMechs. A mere five years later, even
bottom-tier commands were boasting multiple BattleMech companies.
