It doesn't take Cygnus command long to realize that things have gone horribly, unexpectedly wrong. That includes the drop they sent to Max's position. They saw the super heavy units still present as well as all the Reavers in field maintenance position laid out inside the village and assumed that they were victorious but lost communications.
They learned better when Wrath of Carb began shooting down landers. But by that time they had already sent the location a months rations and all new equipment for ten thousand infantry that were inbound with the landers.
The similarity between the two nations landers was remarkable to Max. Both were a flying brick with huge thrusters on one end and doors on the other, with small folding wings for stability and maneuvering in the atmosphere.
