Is their any realistic military game storylines (similar to Metal Gear Solid games or many other Shooter type games) which has a RPG style of gameplay.

I like realistic military storylines and what not but I don't really like Shooters all that much. So as a result I tend not to pay much attention to the shooters that have those types of storylines.

But are there any games that have a realistic military storyline but has an rpg style of gameplay at the same time.
