This device works in the same way as a terrestrial grenade - except that it is more powerful.

The Alien Grenade is the alien version of the standard Grenade. It is functionally similar but can deal more damage. Aliens will often deploy the Alien Grenades against tight clusters of soldiers.
The Alien Grenade is second to the High Explosive in power but is much easier to carry due to its smaller size and weight. The lighter weight and ease of use of the Alien Grenade allows more soldiers to carry heavy firepower into battle.
Alien grenades can be collected from the battlefield so you do not have to manufacture any unless your tactics always involve grenades and big explosions.
As you can end up having a lot of them it may be a good idea to sell some off. If you intend to use some however, keep an ample supply of salvaged grenades instead of using Elerium to manufacture new ones.
This weapon is the number one reason you shouldn't bunch your soldiers together; the aliens prefer to toss a grenade directly to the feet of the nearest soldier who happens to have at least one friend within the blast radius.
Aliens always set their grenades' timer to zero before throwing it, leaving the target no chance to escape the blast.
