But Kincaid, microgrenades would still come in all three flavours. So if you pick the type when buying, you simply can decide which type to use. Wireless grenades come with the benefit of being explodable whenever you want, either immediately or later, but come with the downside of being jammable. Motion is somewhat dodgeable but still hits close when it's a hand-thrown one and so still kills with ease, timed is less risky but also easier to avoid.
