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 force. 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 large unit size, or the addition of Krootox, or both. A flank assault unit will often need support in the form of markerlights to deliver an effective strike. The inclusion of Kroot Hounds is valuable for units in this role, since they allow accurate outflanking without need of a supporting Positional Relay.
In smaller games Kroot units in the flank assault role can strike a decisive blow; as games become larger the amount of firepower that a unit of Kroot can deliver becomes less likely to deliver a game-changing strike. Even in large games however the ability of a flank assault to direct its damage into units which are otherwise hard to reach, whether cheap objective campers or expensive long-ranged shooting units, can add significant value to the limited shooting power of Kroot.Firepower Core
Kroot have some use as the core element of a Tau formation. When equipped with sniper ammunition their offensive potential is significant. With sniper rounds their threat range is usually limited to their maximum range because of the Heavy profile. Alternatively when Krootox are added to the unit it can usefully engage medium vehicles at considerable range and while maintaining mobility. When using pulse rounds they can generate more shots – point for point – than Strike teams but the shots are lower strength and typically have less range. These units operate best in the center of a Tau formation, where they can benefit from cover saves from units on the front lines and buffs from supporting characters and other units. The lack of the Supporting Fire special rule 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 per model and can form a protective screen for units behind them, providing a barrier against assault and a cover save. Additionally 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 positioned or infiltrated ahead of the main Tau force for this role and can be stretched out into long lines which are within Supporting Fire reach of many Tau units behind them. Scout or Infiltrate Blocking
Some armies rely on army-wide Scout or Infiltrate 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 - or an 18" distance if Infiltrating while visible to the Kroot. Table Control
Kroot are cheap enough on a per-model basis and flexible enough in their deployment options that they can be used to establish table control by their physical presence. Well spread out and in sufficient numbers they can protect high value Tau models from attack by short range weapons such as Melta weapons even when those threats can bypass conventional screening by deep strike, outflank or by flying. A distinctive use of this role is in combination with a Void Shield Generator: the Kroot spread out to the limits of the 12” shield zone to prevent enemy units from entering it thus forcing them to shoot through the shields which protect the high value units within.
A fringe use of table control is drop-pod trap deployment. Kroot are deployed in areas where enemy drop-pods are likely to wish to land in circular patterns where the diameter of the circle is the width of a drop-pod plus 1”. Should a drop-pod scatter into this area it will auto-correct to the centre of this circle but there will be no space at all for any models contained in the drop-pod to disembark; as the disembarkation of a unit from its drop-pod is forced the unit contained within will be destroyed. This tactic can be a considerable shock to opponents and in a spirit of sportsmanship should usually be well explained when deploying in this way.Objective Scoring
With their ability to Infiltrate Kroot Carnivores are able to start the game on or near objectives across much of the table. When playing Maelstrom missions, tournament missions with a Maelstrom element or the Relic scenario they can enable a Tau commander to start the game in an advantageous scoring position. With their high body count and respectable unit footprint a unit of Kroot can pre-emptively hold and screen an objective to keep enemy deep-strikers – and especially drop-pods – from claiming them.
Kroot held in Outflank reserves are useful for moving onto objectives later in the game, including objectives in the enemy deployment zone if they are anywhere near the table edges. Adding a hound to the unit of Kroot greatly helps in accurately outflanking into the desired spot for claiming or contesting an objective.
With their limited durability Kroot are rarely able to hold objectives in the open against hostile attack. Where objectives have been placed in good cover Kroot are much better able to hold onto them and thus require a concentrated effort by an opponent to remove.
