Unfortunately, letters are now rarely written. Perhaps only the letters to the army are still as relevant as before. Modern people prefer SMS, but in urgent service it is not always possible to use a mobile phone or the Internet, which is why they write letters to soldiers.
How we do not have enough loved ones when we are forced to part with them for a long time. And how you want to write about your feelings, thoughts, about what is happening at home, tell about the news. How can you write a letter to the army in order to cheer him up, not offend him with something, not upset him, because it is so difficult for him there?
Any letter begins with a greeting. When addressing a loved one, they use the words "dear", "beloved." Then you can write about how you miss and dream of seeing each other as soon as possible. If you know about the upcoming meeting (perhaps you want to come with your parents in the near future), be sure to inform about it, because the good news will cheer up the young fighter.
Further, it is worth remembering what questions your brother asked you in the last letter, and answer them. You can ask what interests you. For example, about how relations with other soldiers are developing, how the commanders treat them, how they are fed, whether he copes with physical activity, about the daily routine.
If you received a photo from your brother, write about how proud you are that he defends the Motherland, note that he has matured, matured, become more serious. You can send him your photo as well, this will allow you to be closer.
Let your brother know about the latest news in your family. Perhaps there is a pet in the house that he loves very much. Write to him about how the pet plays, eats. Your brother will be glad that the animal is healthy and fun. Write that friends are interested in his military service and say hello. Don't give bad news, don't upset your brother. Perhaps everything will work out, and his worries will be in vain.
At the end of the letter, one should wish his brother a successful service, good health, good and loyal friends, and good mood. Write that you are waiting for his letter or see you soon.
