The Imperial Gensoukyou Army is a faction comprised of a coalition of Gensoukyou's factions. It was technically co-founded by Solar, since he had warned that Gensoukyou needed something to defend itself against a larger force. Although the faction had formed a bit late during the Lunarian invasion, leaving the faction confused and scattered. After the incident was resolved, the IGA was fully formed by Reimu Hakurei and Yukari Yakumo.

"I recommend building a force as soon as possible to defend your home from organizations like mine."

That line was said to the Shrine Maiden to form something like that, although the somewhat cryptic advice and moreso, sudden calling from a person barely known was likely more of taken upon the least of concerns. The man had walked away and had only really checked back once. Although it seems that he had predicted such a thing had happened during the Lunarian Invasion. Since then, Gensoukyou was in a complete state of panic and chaos when the Lunarians had invaded. After the incident, most of the forces were in agreement, even the Lunar Outcasts. That Gensoukyou needed a force to dispel such invasions, and not to have it done by the Shrine Maiden herself. What if she wasn't around, after all?

The Imperial Gensoukyou Army had then been formed, a coalition where most groups are on a tense edge, remembering what had happened in the past. But one thing was for certain. Gensoukyou is their home, all of theirs', so it wasn't unusual to see groups within the army fight amongst themselves. Whether it's a playfight or a disagreement, or an actual conflict, none can say for certain, as there has been little recorded deaths at all within these conflicts. Although the coalitions likely will work together on occasion to take down conflict that threaten the area they call home.
