TX-4 Piranha - Known Tactical Formations: Firestream Piranha Wing - When a number of Tau Hunter Cadres fight together, they make use of a higher-level scouting force consisting of a number of Piranha squadrons. These so-called Firestream Wings are often called "Piranha Swarms" by Imperial troops. The are responsible for not only scouting terrain ahead of a multi-cadre force, but also disrupting enemy forces. The primary function of a Firestream Piranha Wing is to hunt and eliminate isolated enemy forces. These Piranhas are often fitted with Seeker Missiles, and their chin-mounted Burst Cannon is replaced with Fusion Blasters; making them exceptionally lethal armour hunters, especially when homing in on Marker Light targets acquired by other units. For this reason, the wing often includes a Tetra scout speeder team to support them in their hunt. A lone Piranha leads the formation, whose crew are a specially designated Target Acquisition Team trained to optimise the firepower of their comrades' craft by spotting vulnerable prey for elimination. The formation's lethal assault is enough to utterly shatter lone enemy formations and eliminate enemy scouting forces wholesale. However, during extended combat operations, the Piranha crews can withdraw; undergoing swift repairs and taking on fresh Drone replacements at their base before plunging back into the fight. The Firestream Wing's secondary function is to disrupt the deployment of enemy forces. They achieve this through a highly complex communications array mounted upon the wing's command vehicle. This array gathers sensor data from all of the Piranhas in the wing, and decrypts any communications it intercepts and identifies. The orders contained in the signal are altered, the encryption re-applied, and the signal reconstructed before being transmitted onwards to the intended recipient. Should the signal prove impossible to replicate, the system is capable of jamming any type of communication it can detect. The re-transmitted signal is intended to disrupt enemy orders, changing dispositions without the enemy command being aware of the subterfuge. Enemy units will often find themselves deployed kilometres out of line, and either ambushed or unable to take part in the battle. Soon, the entire enemy army is in disarray, allowing the Piranha wing and following Tau units to engage the enemy entirely on their own terms. The Tau have become so adept at this process that they can analyse and jam almost any signal, and succeed in disrupting even entirely alien forces whose technology they have not encountered before.Firestream Piranha Squadron - Piranha Firestream Squadrons are intended to provide heavy supporting fire for beleaguered Tau ground forces. They carry extra ammunition for their weapons, but only have a limited amount of fuel. Should a Tau attack falter or a defence line start to crumble, Firestream Squadrons will quickly be despatched from a large central reserve to stabilise the situation, screaming swiftly into battle and using their firepower to stem the enemy attack, before returning to their base to refuel and have any losses replaces before going to battle once more. A Firestream Piranha Squadron consists of five Piranha squadrons as standard.Infiltration Cadre - Infiltration Cadres are expected to advance into harm's way to locate high value strategic targets to attack -- they serve as the eyes and ears of the Fire Caste. Usually operating deep behind enemy lines, the warriors of an Infiltration Cadre are prepared to fight unsupported against superior foes, using every iota of their skills in stealth and evasion to stay alive while hammering the enemy with fire. However, a properly deployed Infiltration Cadre is never truly isolated, for by activating their intervention request beacons or concentrating their Marker Lights in a neutralisation lattice, the Cadre can call in massive reinforcements to screaming volleys of Seeker Missles to turn the tables upon their foe. Infiltration Cadres are usually made up of three Pathfinder teams, two teams of XV25 Stealthsuits, and a TX4 Piranha squadron.
