Clash of Clans is a strategy-based game where you will gain a territory and then you will need to build your base in this territory and keep recruiting soldiers to work for you and participate in various trainings to make your army stronger. Here you have to be careful of all the "neighbors" around you because who knows if he will take advantage of your inattentiveness and then plunder your resources. Do not just focus on the aesthetics when building, but also on defense, only strong enough to not be easily demolished. You need to keep accumulating resources on your way to development and then start building all the facilities that are good for development. Expand your territory by fighting and acquiring new building materials so that you will have a wider territory. The right mix of military formations will allow you to get twice as much work done in defense. And if you want to take revenge then the formation becomes more important, so it is best to take the lead in reviewing the formation of your army before any fight, so that you can minimize losses. 

Next, I will introduce you the formation strategy

1. Grid array

In Clash of Clans, the defensive ability of the lattice array is very strong, while the periphery of the lattice array placed mortar, so as to improve the lattice array AOE damage.

2. Fish array

The fish array is actually a kind of lattice array. The layout of the fish array looks very regular, only used to know the effect of the fish array, I think the fish array is better than the lattice array.

3. Guide array

Guide array is characterized by traps.
