Gu Hang's thinking was quite natural: knowing that Green Skin reinforcements were on their way, it was only logical to try to defeat the enemy at hand before the arrival of the reinforcements.

The terrestrial battlefield of Temir No.5 was unlikely to decide a winner so quickly. Even if you were slaughtering pigs, you couldn't kill billions of Green Skins that fast.
The previous victory Perbov had achieved did successfully disrupt the Green Skin defensive line in one entire direction, throwing the entire planet into chaos due to the loss of their highest commander. Seizing this chance, he efficiently directed his troops, winning several annihilation battles, battles of destruction.
