One last thing to note. I think plawolf and others have argued that the QTS-11's grenades can function as pure concussion grenades. Unfortunately, the MK3A2 concussion grenade, only has a 2 meter killing radius. Moreover, it contains 233 grams of TNT, whereas the QTS-11's grenades have a projected explosive charge of 38 grams. Even when factoring in more modern explosive compositions, the QTS-11's grenades have 79% less explosive power. This gives it roughly only a .9 meter killing radius from the blast itself. Not inconsiderable, but very poor when it comes to concussion grenades.
