Buzzers

The terrifying 'Buzzers' constitute the Scrin's basic anti-infantry units. Buzzers are created in small swarms, with experiments with captured Scrin hardware demonstrating that they may be created quickly and cheaply. Swarms remain together and are guided by what seems to be a limited sentience. Each individual Buzzer is like a floating, high-powered buzzsaw capable of tearing through flesh and light infantry armour plating. Multiple swarms are able to horrifically rip through infantry units, and Buzzers are also able to clear garrisoned buildings. In addition, the Scrin are known to 'combine' their terrestrial vehicles with Buzzer swarms, so that the Buzzers travel with the vehicle and are able to move off and attack enemy infantry when necessary.

The Buzzer Hive, a Scrin base defense, is able to send swarms of Buzzers at attacking infantry. Buzzers have even been known to appear almost out of nowhere, right in the middle of the battlefield.

While they are highly threatening Buzzers are, of course, quite lightly armoured and particularly vulnerable to explosives. They are also completely useless against any form of vehicle, as their 'blades' are not capable of penetrating vehicle plating.
