The blockading of the star system not just prevented the MTA from rapidly reinforcing the Bentheim System.
It also blocked the fleeing outfits from transitioning into FTL!
Fortunately for the cowardly mercenaries, the sandmen weren't interested in hunting them down. The huge number of sandman monoliths instead focused on advancing to the inner system while simultaneously exerting a huge amount of pressure on the MTA task force!
For all of their advanced technology and might, the MTA's Komodo Branch was hardly representative of the Big Two's might!
Underfunded and overlooked within the huge organization, the Komodo Branch had to do more with less.
Their warships were just a bit less fully featured than the warships stationed in the galactic center.
Their multipurpose mechs were a bit less powerful due to the widespread scarcity of high-grade exotics in the galactic rim.
