Outflanking and Infiltrating units of Kroot can be tactically useful in a disruptive role, throwing a proverbial wrench into the enemy's plans. This disruption can be accomplished by using the Kroot to target vulnerable backfield units, draw off assault units from their primary targets, or even threaten objectives in the enemy deployment zone. Since Kroot are a scoring unit; they can pose a threat beyond their offensive potential. The inclusion of Kroot Hounds is key for units in this role, since they allow accurate outflanking. Flank Assault:
Large units of Kroot can be outflanked offensively to attack the enemy in a substantial way (greater than disruptive attacks). With a positional relay in position near the enemy's table edge, they could even arrive behind
enemy forces. These units need substantial offensive power to function in their role, in the form of sniper ammunition and/or Krootox. As in disruption, the inclusion of Kroot Hounds is key for units in this role, since they allow accurate outflanking. A positional relay reduces the benefit of including a Kroot Hound, since it eliminates the outflank roll, however positional relays are subject to enemy action and other perils. Given the other benefits of Kroot Hounds, there is good reason to bring a one even if planning to use the positional relay. Firepower Core
Kroot are also useful as the core element of a Tau formation. When equipped with sniper ammunition their offensive potential is significant, but limited to their maximum range, and firing sniper rounds is a 'Heavy' shooting attack, reducing mobility. Kroot benefit greatly from the presence of an Ethereal, whom increases their leadership and can augment their survivability or firepower. These units operate best in the center of a Tau formation, where they can benefit from cover saves from units on the front lines. The lack of supporting fire is a notable deficiency of the Kroot in this role.Screening:
Kroot can also be employed as a screening unit for a larger formation. They are inexpensive, and can form a protective screen for units behind them, providing a barrier against assault and a cover save. In addition, A Kroot unit spread out across the front of a Tau formation can benefit from many sources of overwatch via supporting fire. The Kroot's capacity for high model count makes them uniquely well-suited to the role of overwatch-collectors. Kroot can be infiltrated ahead of the main lines for this role. While Kroot are not a melee unit, they can be used in a tarpit role, if supported by Ethereal-boosted leadership and the stubborn special rule via Calm of Tides or attachment of an Ethereal.Counter-Infiltration:
Some armies rely on army-wide scout moves to close the distance with enemy forces. Units of Kroot can be infiltrated ahead of the main Tau force in order to push back enemy infiltration and scout moves. Even a small unit of Kroot can be effective in this role, as the enemy forces will have to maintain a minimum distance of 12" from the Kroot after scout moves, or during infiltration (18" if they are visible).
