A soldier course is a bricklaying pattern where bricks are laid vertically with their long, narrow sides facing outwards. In this pattern, the bricks are aligned in a single row, creating a uniform and distinctive appearance reminiscent of a row of soldiers standing at attention, hence the name "soldier course."

Soldier courses are commonly used for decorative purposes or to create architectural features such as window and door surrounds, corners of buildings, or raised borders in paving projects. They can also be used to add visual interest or emphasis to a particular area of a brick wall.

In addition to their aesthetic appeal, soldier courses can provide structural reinforcement and help create clean, crisp lines in brickwork. They are typically laid with mortar joints between the bricks, although dry stacking (without mortar) can also be used for certain applications.

Overall, soldier courses are a versatile and visually striking bricklaying pattern that can be used to enhance the appearance and structural integrity of brick walls and other masonry structures.
