Military spending space

Hello
I want to know how upgrade my military spending space of my army, i want to create more fleet, but i cant.

13 products were not ordered because the country has no more military spending space.

someone can help me please?

There are two ways: 1. Pay 1 GC to get a booster. 2. Write down what you need and order it manually month by month. Immediate orders like the one you mention above always finish your spending space quickly.
