According to the information provided, I recommend The Marvel World's Armor Warrior. This light novel, a derivative of the fanfiction, told the story of an advisor who became an armored warrior. He once fought alongside Captain America. Therefore, the protagonist and Iron Man's father, Captain America, had indeed served in the army together. I hope you like my recommendation. Muah ~

Yes, Iron Man 1 did have the image of Captain America's shield.

In the Marvel Cinematic Universe, Iron Man and Captain America appeared together in the Avengers series. This was the first time the two had worked together in a movie.

From then on, the two of them often appeared together in movies, bringing many exciting battle and cooperation scenes to the audience.

In the comics, Iron Man did not kill Captain America. Their conflicts and battles were part of the storylines, but not to the extent of one killing the other. The relationship between them was complex but not fatal.

This book was called " The Armor Warrior in the Marvel World." The protagonist traveled to Captain America, Captain America, and Howard Stark to fight together. Later, he traveled to Iron Man and became Iron Man. I recommend this book to you. I hope you will like it.😋

I'm not sure exactly, but there are a few. It depends on how you count different editions and special releases.

In the world of fanfiction, the idea of Iron Man killing Captain America can be quite controversial. Ethically, it goes against the typical heroic and friendly relationship they have in the mainstream Marvel universe. However, fanfiction is a space for exploring different scenarios, so while it may seem unethical to some, it can be a creative exploration for others.

A third common theme is sacrifice. Fanfictions may depict situations where either Captain America or Iron Man has to sacrifice something for the greater good or for the sake of their relationship. It could be something as simple as sacrificing personal time to train together or as big as sacrificing a chance at personal glory to save the other.
