What is the standard posture of standing at attention, being at ease and saluting?

Attention: The heels are close together, and the toes are about 60 degrees apart. Straighten your legs, slightly contract your abdomen, and naturally stand out. Upper body upright, slightly forward. The shoulders should be flat and slightly backward. The arms droop naturally and the fingers bend slightly when they are together. The tip of the thumb is attached to the second section of the index finger, and the middle finger is attached to the trousers seam. Keep your head straight, your neck straight, your mouth closed, your chin miniature and your eyes straight ahead.

Key points at ease: On the basis of standing at attention, the left foot extends about two-thirds of the whole foot along the toe direction, the legs are naturally straight, the upper body remains at attention, and most of the body's center of gravity falls on the right foot. When holding a gun (barrel, cannon), the carrying mode remains the same, and other actions are the same as unarmed. If you feel at ease for too long, you can change your feet yourself.

Salute essentials: the upper body is upright, the right hand is quickly lifted by cutting corners, and the five fingers are naturally close together. The middle finger is slightly connected about 2 cm in front of the right corner of the brim, with the palm down and slightly outward (about 20 degrees). The wrist is not allowed to bend, the right arm is slightly flat, slightly in line with the shoulder, and at the same time look at the subject.

Standing posture, also known as "pulling posture", is the first lesson for soldiers and a skill that must be learned in military training. Standing on the military posture can be said to be the mother of all military actions. At the same time, the military posture also contains profound significance.
