WALLS (WOOD, STONE, ETC.)
Rust Walls have easy-access sides to them and that is where you want to access a base from.
The strong wall is on the left side. The outside side of a wall will have more textures and will look more high quality. This is a strong wall which will take longer than the inside wall.
The weak wall is on the right side. The inside side of the wall is the weak side of a wall (wood, stone, etc.). This side has less textures than the outside wall and will be easier to break into. This side of the wall will have way less health, it is better to break into in all ways. Not all bases will have these weak walls.
JUST REMEMBER, the weak side of the wall will have less textures, look less important and will not be as standing out as the outside wall. The strong side will have more textures and look more important than the inside.
TIPS FOR BREAKING IN
For breaking into the weak walls people will usually just use wooden spears. People usually use this tactic if they have multiple people with them.
