Russia is in a war. The war costs a lot of money. Russia spends a lot on its military. This is for soldiers and weapons.
The government has a problem now. The country's economy is not strong. They cannot keep spending so much money on the war.
The plan for next year is different. The military budget will be smaller. This means there is less money for the army.
The war will not stop. But it will be a slow fight. Russia must be careful with its money.
