退伍軍人 is the Chinese title for a military veteran.

The first two characters mean “retired from the ranks,” or discharged.

The last two characters mean serviceman, soldier, or military personnel.

軍 means army, military, or arms.

軍 is also a character used in the compound word that means “army general.” It's the “gun” in the well-known Japanese title “Shogun” which means general.

現役軍人 means “Active Duty Soldier” or literally “Active Duty Military Person.”

This title is a great way to show pride in being an active duty member of the armed forces.

The first two characters mean “active duty” and the second two characters can mean “military personnel,” “soldier,” or “serviceman” (it is unisex, so male or female is not indicated).

軍人 means “Soldier” or literally “Military Person.”

This can also be translated as “military personnel,” “soldier,” or “serviceman” (it is unisex, so male or female is not indicated).

軍事情報 is the full way to say “Military Intelligence.”

The first two characters mean “military affairs.”

The second two characters mean “intelligence” or “information-gathering.”

If you work in the G2 section of your military unit, this is the wall scroll for you.

工兵 means the “engineering corps” of the army or other branches of the military.

The first character alone means work, worker, skill, profession, trade, craft, construction, or labor. The second character means army, force, or military.

海兵 is a way to express “Marine” as in an individual “Soldier of the Sea” in Japanese Kanji and old Korean Hanja characters (not to be confused with Korean Hangul).

Breaking down each character, this means:
“ocean/sea soldier/army/warrior.”

Please note that this Japanese/Korean version roughly means “sailor” or “navy” in Chinese.

兵 can be used to express soldiers, troops, a force, an army, weapons, arms, military, warfare, tactics, strategy, or warlike.

The final meaning depends on context. It's also part of the Chinese title for the Terracotta soldiers. In fact, this character is usually used in compound words (words of more than one character). Sometimes this single character is the title used for the pawns in a chess game (in a related issue, this is also a nickname for soldiers with the rank of Private).

孫子兵法 is the full title of the most famous book of military proverbs about warfare.

The English title is “Sun Tzu's The Art of War.”

The last two characters have come to be known in the west as “The Art of War,” but a better translation would be “military strategy and tactics,” “military skills” or “army procedures.”

Note: Sometimes the author's name is Romanized as “Sun Zi” or “Sunzi.”

It's written the same in Chinese, Japanese Kanji, and Korean Hanja.

兵法 means “Art of War.”

It is also part of the title of a famous book of tactics by Sun Tzu. 兵法 could also be translated as “military strategy and tactics,” “military skills” or “army procedures.” If you are a military tactician, this is the wall scroll for you.

海軍陸戰隊 is the Chinese way to express “Marine Corps.” This could be the Marine Corps of virtually any country that has an amphibious military force.

Let me know if you want a more specific title, such as British Royal Marines or U.S. Marine Corps.

The Chinese title for Marines is very verbose...
Breaking down each character this means:
“ocean/sea military/arms shore/land fighting/war/battle corps/team/group.”

水兵 are the Chinese and Japanese characters for “Sailor.”

Specifically, this refers to an enlisted sailor.

These two characters literally mean “water soldier.”

海軍陸戰隊員 is the Chinese way to express “Marine.” (as in a member of the Marine Corps). It is not country-specific, so it could be the Royal Marines, U.S. Marines, Chinese Marines, etc.
In Australian English, they would translate this as “Naval Infantryman.”

Breaking down each character this means:
“ocean/sea military/arms shore/land fighting/war/battle corps/team/group person/member.” Note that the first two characters are presented together but outside of this phrase mean “navy” (sea military).

海兵隊 is the Japanese and Korean way to express “Marine Corps” or simply “Marines.” It is not specific, so this can be the Marine Corps of any country, such as the British Royal Marines to the U.S. Marines.

Breaking down each character, this means:
“ocean/sea soldiers/army corps/regiment/group.”

米海兵隊 is the Japanese way to write “United States Marine Corps” or simply “U.S. Marines.”

Breaking down each Kanji, this means:
“rice (American) ocean/sea soldiers/army/military corps/regiment/group.”

This title will only make sense in Japanese, it is not the same in Chinese! Make sure you know your audience before ordering a custom wall scroll.

If you are wondering about rice, America is known as “rice country” or “rice kingdom” when literally translated. The Kanji for rice is often used as an abbreviation in front of words (like a sub-adjective) to make something “American.” Americans say “rice burner” for a Japanese car and “rice rocket” for a Japanese motorcycle. If you did the same in Japanese, it would have the opposite meaning.

Note: I have not verified this but I’ve found this title used for U.S. Marines in Korean articles, so it’s most likely a normal Korean term as well (but only in Korean Hanja).
