The ruling on military personnel if they enter the state of ihram in their official uniforms

Question:
Some military personnel are prevented from performing Hajj, so do they enter the state of ihram in their military uniforms?

Answer:
Likewise, they have the same obligation as one who shaves his head. One who is compelled to wear [the uniform] must observe this expiation: feeding six poor people, or slaughtering a sheep, or fasting for three days.
Q: Is the belt that is worn with the ihram garments considered sewn clothing?
A: It does not harm. The belt does not harm. There is nothing wrong with a belt for the lower garment.
Q: Do military personnel cover their heads with a cap and wear the uniform?
A: If they are compelled to do so while in the state of ihram, they must pay the expiation; an expiation for the head, and an expiation for the body: feeding six poor people for the head, and six poor people for the body, or slaughtering a sheep for the head, and slaughtering a sheep for the body, or fasting for three days for the head, and three days for the body. The head is distinct from the body.
