In terms of services:
Army: You are fully qualified to be an ordinary infantry, and you are likely to be a top trainer. There is a great possibility of promoting non-commissioned officers. You can also join a certain group of agents as scouts through the exam. This is your most likely and sure future.
The height of armored soldiers cannot be higher than 1.75m, so you are not suitable.
Artillery requires a lot of physical strength, but if you go, it will be a waste of talent and you won't be too interested.
Radar/wired communication, electronic countermeasures, mechanical maintenance, weapon maintenance and other technical arms are not your strong points.
Let's not talk about the logistics support arms. It is a waste for you to go. Don't go, including the corpsman.
Navy: You didn't ask for water, anti-seasickness, anti-noise and anti-loneliness. You also said that you like licking blood with a knife, which is definitely not suitable for you. Navy soldiers often can't see the enemy for months, so they must endure loneliness, or they will be a collective time bomb and won't let you get on board. Submarine soldiers have the highest subsidy, but the highest requirements. Your height is too high to be appropriate.
Air Force: Pilots have height requirements, and you are not suitable. Most of the technical arms on the ground are ground support, which is not your specialty.
Marine Corps: It suits your specialty. You are seasick because of your poor water skills. Just try it. Absolutely challenging. It is called the sea dragon and the earth tiger.
Special brigade: soldier king. Physical strength, fighting, firearms, driving, ships, foreign languages, blasting and reconnaissance are all first-class levels. Generally, you can only choose from top veterans or officers in all aspects, and it is impossible to choose from recruits. You are only physically qualified now, and you are not sure about culture, foreign languages and actual combat experience, so it is unlikely.
Finally, advice: field army infantry-top trainer-squad leader/platoon leader-spy company scout-war hero, your most likely career path.
