I wanted to see what Torah says about military service and what kind of advice Torah can give to a soldier. Let's take a look at Numbers 26:2 first:
YLT Num 26:2 'Take up the sum of all the company of the sons of Israel, from a son of twenty years and upward, by the house of their fathers, every one going out to the host in Israel.'
This verse tells us that the age for military service is 20 years old. At this age a man is usually ready, mentally and physically, for the military service and war. So if you want to join a military, do not join before you are 20. This way it is going to be easier for you.
First of all, each Soldier MUST KNOW THE 10 COMMANDMENTS and always remembers them during the war and battle.
Now, let's take a look at other verses. Deuteronomy 20:1-20.
YLT Dt 20:1 'When thou goest out to battle against thine enemy, and hast seen horse and chariot--a people more numerous than thou--thou art not afraid of them, for Jehovah thy God is with thee, who is bringing thee up out of the land of Egypt;
YLT Dt 20:2 and it hath been, in your drawing near unto the battle, that the priest hath come nigh, and spoken unto the people,
YLT Dt 20:3 and said unto them, Hear, Israel, ye are drawing near to-day to battle against your enemies, let not your hearts be tender, fear not, nor make haste, nor be terrified at their presence,
YLT Dt 20:4 for Jehovah your God is He who is going with you, to fight for you with your enemies--to save you.
YLT Dt 20:5 'And the authorities have spoken unto the people, saying, Who is the man that hath built a new house, and hath not dedicated it?--let him go and turn back to his house, lest he die in battle, and another man dedicate it.
YLT Dt 20:6 'And who is the man that hath planted a vineyard, and hath not made it common?--let him go and turn back to his house, lest he die in battle, and another man make it common.
YLT Dt 20:7 'And who is the man that hath betrothed a woman, and hath not taken her?--let him go and turn back to his house, lest he die in battle, and another man take her.
YLT Dt 20:8 'And the authorities have added to speak unto the people, and said, Who is the man that is afraid and tender of heart?--let him go and turn back to his house, and the heart of his brethren doth not melt like his heart;
YLT Dt 20:9 and it hath come to pass as the authorities finish to speak unto the people, that they have appointed princes of the hosts at the head of the people.
YLT Dt 20:10 'When thou drawest near unto a city to fight against it, then thou hast called unto it for Peace,
YLT Dt 20:11 and it hath been, if Peace it answer thee, and hath opened to thee, then it hath come to pass--all the people who are found in it are to thee for tributaries, and have served thee.
YLT Dt 20:12 'And if it doth not make peace with thee, and hath made with thee war, then thou hast laid siege against it,
YLT Dt 20:13 and Jehovah thy God hath given it into thy hand, and thou hast smitten every male of it by the mouth of the sword.
YLT Dt 20:14 Only, the women, and the infants, and the cattle, and all that is in the city, all its spoil, thou dost seize for thyself, and thou hast eaten the spoil of thine enemies which Jehovah thy God hath given to thee.
YLT Dt 20:15 So thou dost do to all the cities which are very far off from thee, which are not of the cities of these nations.
YLT Dt 20:16 'Only, of the cities of these peoples which Jehovah thy God is giving to thee for an inheritance, thou dost not keep alive any breathing;
YLT Dt 20:17 for thou dost certainly devote the Hittite, and the Amorite, the Canaanite, and the Perizzite, the Hivite, and the Jebusite, as Jehovah thy God hath commanded thee,
YLT Dt 20:18 so that they teach you not to do according to all their abominations which they have done to their gods, and ye have sinned against Jehovah your God.
YLT Dt 20:19 'When thou layest siege unto a city many days, to fight against it, to capture it, thou dost not destroy its trees to force an axe against them, for of them thou dost eat, and them thou dost not cut down--for man's is the tree of the field--to go in at thy presence in the siege.
YLT Dt 20:20 Only, the tree, which thou knowest that it is not a fruit-tree, it thou dost destroy, and hast cut down, and hast built a bulwark against the city which is making with thee war till thou hast subdued it.Torah also reminds one to observe hygiene during the war. It is Deuteronomy 23:9-14
YLT Dt 23:9 'When a camp goeth out against thine enemies, then thou hast kept from every evil thing.
YLT Dt 23:10 'When there is in thee a man who is not clean, from an accident at night--then he hath gone out unto the outside of the camp--he doth not come in unto the midst of the camp--
YLT Dt 23:11 and it hath been, at the turning of the evening, he doth bathe with water, and at the going in of the sun he doth come in unto the midst of the camp.
YLT Dt 23:12 'And a station thou hast at the outside of the camp, and thou hast gone out thither without,
YLT Dt 23:13 and a nail thou hast on thy staff, and it hath been, in thy sitting without, that thou hast digged with it, and turned back, and covered thy filth;
YLT Dt 23:14 for Jehovah thy God is walking up and down in the midst of thy camp, to deliver thee, and to give thine enemies before thee, and thy camp hath been holy, and He doth not see in thee the nakedness of anything, and hath turned back from after thee.
Torah provides EXTREMELY IMPORTANT instructions in Deuteronomy 21:10-14 as well. This is about the 7th commandment. Please do not engage in sexual crimes at war time.
YLT Dt 21:10 'When thou goest out to battle against thine enemies, and Jehovah thy God hath given them into thy hand, and thou hast taken captive its captivity,
YLT Dt 21:11 and hast seen in the captivity a woman of fair form, and hast delighted in her, and hast taken to thee for a wife,
YLT Dt 21:12 then thou hast brought her in unto the midst of thy household, and she hath shaved her head, and prepared her nails,
YLT Dt 21:13 and turned aside the raiment of her captivity from off her, and hath dwelt in thy house, and bewailed her father and her mother a month of days, and afterwards thou dost go in unto her and hast married her, and she hath been to thee for a wife:
YLT Dt 21:14 'And it hath been--if thou hast not delighted in her, that thou hast sent her away at her desire, and thou dost not at all sell her for money; thou dost not tyrannize over her, because that thou hast humbled her.
As you can see, all of these instructions are self-explanatory and very easy to do.
