Fireblade
Fireblades (or Shas'nel in Tau) are members of the Tau Fire Caste. Consisting of the most grizzled and seasoned veterans of their Cadre, their skills in the art of the Fire Warrior way of battle has led them to eschew Battlesuit technology, preferring instead to be equipped with a Pulse Rifle and Bonding Knife. Fireblades typically serve as field commanders and their experience on the battlefield has made them experts in directing firepower to maximize damage to enemy targets. Owing to their status, Fireblades also wear heavier armour in addition than standard Fire Warriors.
Despite their name and choice of equipment, don't expect the Fireblade to do much CQC especially when he/she is going up against psychotic Supermen with Chainaxes, sociopathic Supermen with Chainswords, thuggish walking mushrooms with steroid injections, fast as lightning elites that can strike without warning, fast as lightning super sadists that can strike without warning, brazen men that will drown you with their own blood and bayonets, scary cybernatic killmachines that has literal aimbots, soulless terminators that can rend your atoms with a scratch, half-naked nutjob ladies that will charge you with a giant chainsaw, voracious outer-galactic space bugs that will eat you, ethereal horrors that can bend the laws of reality over just to get close to you, uncommunicative cyborgs covered in rad-weapons and sharp bits and swarming insects with an empire larger than you and have weapons that can scare off the IoM itself.
The path that the Fireblades have taken mean they can never rise to the rank of Shas'o, instead being limited to that of Shas'el. Nor does the title carry the esteem associated with those who wear Battlesuits. Nonetheless, the Fireblades are still highly respected, not least because of their willingness to forgo prestige.
