The United States Army mod in Grand Theft Auto V is a comprehensive mod that brings the formidable might of the U.S. military to the game. With this mod, the player can avail various types of army vehicles, ranging from tanks, armoured cars, guns and helicopters, all designed to replicate real-life U.S. military hardware. 

You can also switch the standard playable characters with U.S. military personnel, complete with authentic uniforms. This mod also introduces new missions and tasks related to the U.S. Army, creating a more immersive experience that closely reflects the military operations. 

Additionally, the player can interact with the AI-controlled army personnel which offers an in-depth military experience with a high degree of realism. This mod gives an edge to players who want their gameplay filled with more combat and strategy. 

However, please do note that the increased military presence also leads to higher difficulty levels, making GTA 5's world more intense and challenging. Always remember to check the compatibility with your game version, and install as per instructions provided by the mod creators.
