In a narrow hallway type scenario, a rifle, smg, shotgun, and even pistols would likely do the job just as easily. The targets movement is limited and they are effectively channeled into a terrain dictated kill zone. This works best for attackers fighting just out of door ways or around corners firing into the hall.

Who watches the watchmen?De Marquis: That is assuming you have somewhere to dive to. There is also the issue of the hall way channeling the blast back at the person who threw the explosive. Most grenades in urban combat are suited to use in areas where you can attack from a position of cover regardless of grenade type being used.
Ballistic shields have some use in Urban combat but the ones truly able to stop rifle fire and provide the best coverage are not exactly bearing high marks in the portability department. They are large, cumbersome, heavy, and many actually roll around on wheels on the bottom of the shield. They also typically take up a free hand. There are smaller and lighter shields but many trade off levels of protection and area of coverage for portability.

Who watches the watchmen?You are not going to be diving around. The grenades are used when you already have cover as in you are in cover especially when you are in that situation. Even then you are not going to be leaping out into a hall to throw the grenade you throw it from cover minimizing your exposure. If you are having to dive around you are very likely doing something wrong and will be dead in short order.

Who watches the watchmen?how about we deep fry the enemy?
and by deep fry, i mean trap in an area we fill with a flammable gas, so that when they open fire, they blow themselves up instead.
well than it wouldnt be deep frying them now would it, come to think of it, mine wasn't deep frying either, but it involved surrounding something in a fluid substance.

Well more or less what you just described is Fuel Air Weapons or Thermobaric weapons. They scatter a fuel or particulate explosive into the air with a weak dispersing charge and then a second charge sets off the dispersed substance creating an intense hot explosive blast.
A good general description
