Is it possible to produce so many troops?

I am green and I was surprised by the ability of blue to produce so many troops
without entering into deficit.
I earned a little more money than him and went into a deficit
he produced 1200 troops and I 650

He probably was imperialist and spammed infantry while you spammed other more expensive units.
