I told my men to hold fire, keep low and enter stealth mode. Then I ran down the bushes to your left, and told my men to target the two soldiers on patrol. When the soldiers were walking towards the opposite direction, I ran past them, next to the building where the hostages were (Or the garden rather). Told my men to open fire, and I killed the soldiers in the garden. The shooting took about 5 seconds, just like in the movies . Stealth and unintelligent AI are your friends.
