Protect your yellow flag, but do not sit in the trenches, but move towards the enemy, driving him from a high-rise and breaking head to head. You will control your army from the side. At the bottom of the panel there are round icons with painted weapons. Click on them when they are active to add another fighter. The better the weapons, the higher the cost of the soldier. When you get enough fighters, click on the arrow above them to send them to the attack. Make sure that the number of your squad does not fall, otherwise the enemy will quickly take advantage of this in the Army Block Squad.
