Which of the following is considered a basic US flag used by the Army?

The storm flag is considered a basic U.S. flag used by the Army primarily because it is specifically designed for use in inclement weather conditions. This flag is typically smaller than the national flag, allowing it to withstand harsh weather and high winds, making it suitable for display when the larger flags might be at risk of damage. The storm flag plays an essential role in maintaining military protocol and standards for flag display during adverse weather, reflecting the Army's commitment to the proper handling and representation of flags.

In contrast, the national flag represents the country and is used for general display. The service flag is utilized to signify that a family member is serving in the military but does not classify as a basic flag for daily Army operations. The all-weather flag is crafted for durability but is not typically recognized as a standard basic flag within military protocol like the storm flag. Understanding these distinctions helps clarify the specific purposes and contexts in which each flag is utilized within the Army.
