The different color bands are for the different types. Listed below: Regular variant (Green): Upon impact (or if set, a timer) it detonates. Releasing 50 smaller grenades, across a changeable radius (user can set it to any size radius up to 50 meters, or keep it as the default 5 or 10 meters). Half of the explosive force in the whole Cluster can destroy a metal/concrete wall, and covers a large (3-10) meter radius. Fragmentation variant (Brown): Upon impact (if set, then a timer instead of impact) it detonates. Releasing not only 20 smaller grenades, similar to the regular variant, but also 100,000 pieces of shrapnel moving at 500 feet per second. High Explosive variant (Blue): On impact or timer detonation, releases 50 smaller grenades, and is similar in every way to the regular variant. However, the difference is that each of the deployed grenades have triple the explosive power. Incendiary variant (Red): On impact or timer detonation. Variable radius. Not only releases 5 high explosive grenades, but sends out 30 grenades that light a 10 meter (radius) circle on fire each, with the fires burning between 5 and 10 thousand degrees Fahrenheit. There are other variants, however, they are mismatched combinations of the other variants.
