I want to know the answer to the following question:
What was Chiang Kai-Shek's strongest army?
All the background I'm provided with is that "Of the 1,200,000 troops under Chiang's control, only 650,000 were directly controlled by his generals, and another 550,000 controlled by warlords who claimed loyalty to his government; the strongest force was the Szechuan army of 320,000 men.". Is that enough to answer the question?
Answer: yes
