Which flag is the smallest among the three types mentioned?

The storm flag is the smallest of the three flag types mentioned. The storm flag is designed to be flown in severe weather conditions, and its smaller size allows it to withstand high winds and harsh elements without becoming damaged. This practicality serves a critical purpose, ensuring that the flag remains visible and intact even in adverse weather conditions.

In contrast, the garrison flag is significantly larger and intended for display during ceremonial occasions and when the weather is more favorable. The post flag is also larger than the storm flag and is used for regular flag displays at military installations. Understanding the specific dimensions and intended uses of these flags highlights why the storm flag is the compact option among them.
