I see your point. I don't see anyway without family or friends that are like family.
The KJV and YLT translation says,
Deu 24:5 When a man hath taken a new wife, he shall not go out to war, neither shall he be charged with any business: but he shall be free at home one year, and shall cheer up his wife which he hath taken.
Deu 24:5 `When a man taketh a new wife, he doth not go out into the host, and one doth not pass over unto him for anything; free he is at his own house one year, and hath rejoiced his wife whom he hath taken. (?)
So I think you and others are correct that it is only talking about the military or some other type of service that would take the man away from home for an extended period of time.
