How would you say this?
So recently some K-ARMYs have been sending me words of encouragement. It's hard to reply back as I'm just beginning to learn but I want to know how to say "I-ARMYs love K-ARMYs. You're all so sweet." I'm not sure how to spell i-army or k-army. Do you sound it out? Just for future reference. :^)

Question

Answer

Here's the answer:
우리 아이아미는 케이아미 여러분을 사랑해요. 여러분 모두 정말 멋져요.
Uri I-ARMYneun K-ARMY yeoreobuneul saranghaeyo. Yeoreobun modu jeongmal meotjyeoyo.

Now I'll explain how to actually pronounce them and what do they exactly mean, phrase by phrase:

우리 아이아미는: Oo-ri ai ami noon
This means: "We, I-ARMYs (Subject)"

케이 아미 여러분을: kei ami yo-ro-boon ul
This means: "you, people of K-ARMYs (Object)"

사랑해요: sa rang he yo
This means: "love (Verb)"

여러분 모두: Yoroboon mo-doo
This means: "You all (Subject)"

정말: jung mal
This means: "really (Adv.)"

멋져요: mot jyo yo
This means: "(are) sweet. (*Ad.)"

Note:
In Korean, adjectives(형용사) modify subjects, like "be + Ad." in English.
And the role of adjectives in English(modifying nouns directly) is substituted by 'prenouns(관형사)' in Korean.

I hope this helped you. ('<')
