When the remaining United Federations General Robot (UFGR) Mechas reached the land, the MG Gunners were targeting them without mercy. Some tried to land with some obstacles to reduce contact with the MG Gunners but they were not successful.
Initially, they thought that they had the numbers until they realised that there were more MG Gunners that were hiding within the synthetic forest after descending into the space colony while there were some who kept themselves inactive until those UFGR reinforcements came.
With the loss of support from the Rook Class Warship Chariot XIII, they were at an extremely significant disadvantage especially when the remaining MG Gunners came out and sniped them from their camping positions.
