"Clash of Clans" is a strategy mobile game. Players protect their villages by building and upgrading buildings, training troops, and attacking other players to obtain resources. The game combines multiple elements such as construction, strategy, and battle. Players need to reasonably lay, defend attack, and challenge opponents from all over the world.

The following defense facilities are more suitable for defense on the outer layer:

1. Arrow tower: fast attack speed, moderate range, can quickly strike enemies close to the outer layer, whether ground or air targets.

2. Cannon: mainly aimed at ground targets, with high single-shot damage, can effectively resist the early attack of ground forces.

3. Anti-aircraft rockets: If the enemy often uses air force attacks, appropriately placing anti-aircraft rockets on the outer layer can attack air units as early as possible.

4. Tesla electromagnetic tower: its hidden characteristics can cause unexpected attacks on the enemy, and placing it on the outer layer can disrupt the enemy's offensive rhythm.

Placing these defense facilities on the outer layer can cause damage to the invading enemy forces in advance, and buy more reaction time for the core defense facilities in the inner layer. However, the specific layout needs to be adjusted according to the overall formation of your tribe and the common attack methods of the enemy.

The following defense facilities are usually more suitable for defense in the inner layer of the tribe:

1. Hell Tower: The damage will continue to increase when the same target is continuously attacked. It has a strong restraining effect on the enemy's high-health soldiers or heroes. It is one of the core forces of the inner layer defense.

2. Mage Tower: It can attack multiple targets at the same time, has range damage, and can effectively deal with the enemy's cluster charge.

3. Bomb Tower: It can cause a lot of group damage when the enemy is dense. Placing it in the inner layer can cause a heavy blow to the enemy who breaks through the outer layer defense.

4. Mortar: Although the attack speed is slow, the range is long and the range is large. It can cover most areas of the tribe in the inner layer and carry out range bombing on groups of enemy troops.

Placing these facilities with strong defensive capabilities in the inner layer can give the enemy a fatal blow after breaking through the outer defense, thus protecting the important buildings and resources of the tribe to the greatest extent.

There are some specific tips and precautions for the placement of defensive facilities:

1. Corner placement:
- Anti-aircraft rockets or arrow towers can be placed in the corners of the tribe, which can maximize their attack coverage and reduce defensive blind spots.
- But be careful to avoid being easily destroyed by the enemy with long-range soldiers or spells.

2. Surrounding important buildings:
- Place defensive facilities around resource storage facilities (such as vaults, holy water reservoirs, etc.) or base camps to form a key protection area.
- For example, placing the Hell Tower near the resource library can effectively deter enemies who try to rob resources.

3. Use city walls to block:
- Some defensive facilities can be placed behind the city walls, so that the enemy needs to break through the city walls before attacking the defensive facilities, increasing the difficulty and time cost of the enemy's attack.
- But be careful to avoid being completely blocked by the city walls.

4. Disperse and space:
- Do not place similar defense facilities next to each other to prevent multiple facilities from being destroyed at once by the enemy's lightning spell or earthquake spell.
- Keep a certain distance so that they will not be damaged at the same time when attacked.

5. Consider the attack direction:
- According to the map and the common enemy attack direction, reasonably adjust the direction of the defense facilities to ensure that the enemy can be attacked the first time.
- For example, if the enemy often attacks from the left, the defense facilities on the left can be appropriately strengthened.

6. Avoid straight line arrangement:
- Do not arrange the defense facilities in a straight line, which makes it easy for the enemy to quickly break through with arms such as wild boar riders.
- Use a staggered layout to increase the difficulty of the enemy's attack route selection.

7. Cooperate with traps:
- Place traps near the defense facilities, such as spring traps, bombs, etc. When the enemy is attracted by the defense facilities, the traps are triggered to cause additional damage.

8. Leave some open space:

- Don't fill all the space in the tribe with defense facilities. Leave some open space to confuse the enemy and facilitate the deployment of reinforcements.

In short, the placement of defense facilities needs to take into account multiple factors and constantly adjust and optimize according to actual combat experience to adapt to different enemy tactics.

In "Clash of Clans", the placement of defense facilities of different levels may have the following differences:

Low-level defense facilities:

1. Due to relatively weak defense capabilities, they may be placed more in the outer layer to serve as early warning and preliminary blocking of the enemy. For example, low-level arrow towers and cannons can be placed at the forefront of the tribe to attract enemy forces and buy attack time for the high-level defense facilities in the inner layer.

2. Place them in a dispersed manner to avoid being easily destroyed by the enemy's concentrated firepower, because the health and defense of low-level facilities are low.

High-level defense facilities:

1. They are usually placed closer to the core area or important buildings to provide stronger protection. For example, high-level hell towers and wizard towers will be placed near key locations such as resource libraries and base camps.
2. Concentrate on the direction where the enemy may focus on attacking, forming a strong cross-fire area, and enhancing the ability to strike high-value targets of the enemy.
3. Due to the high attack range and damage of high-level defense facilities, they can be placed in relatively more concealed positions to cause significant damage to the enemy unexpectedly.

It should be noted that the specific placement also needs to be flexibly adjusted according to the overall layout of the tribe, the structure of the city wall, and the common offensive strategies of the enemy to achieve the best defense effect.
