Calliban have access to some unique and rare weapons bringing Nanopulsers, Assault Pistols, and a Feurbach on various profiles. All but one of their profiles comes with D-charges making them useful for taking out objectives or enemy that have been immobilized. Their decent BS of 12 means they are not bad shots. The Inferior Infiltration profiles can also be used to get a model across the midfield for a better offensive position.
Generally speaking Calibans are intended for close range firefights, wanting to be in the 0"-16" range band.
AR 2 and BTS 3 means that Caliban are harder than the average infantry but are still vulnerable to heavier weapons or bad luck.
They have access to AutoMediKit on all profiles however meaning that players should take care to think of where the trooper will end their movement. Moving into then out of line-of-fire is best, or assuring that the model is behind a barrier so they will drop out of line-of-fire if knocked unconscious are best. This will allow you to use the AutoMediKit without provoking an enemy ARO. Also remember that multiple models can use a Coordinated order to all AutoMediKit at once forcing less ARO or allowing you to efficiently recover multiple troopers.
This profile has the Spawn Embryo rule. When the unit is unconscious, it still counts as a scoring unit for scenarios like Quadrant Control or Supremacy. Armies with large numbers of Shasvastii sectorial players might consider taking out enemy units with Shock, Viral, or Monofilament as a higher priority to exploit this rule.
Caliban have access to a Link-able Feurbach in the Shasvastii Sectorial which is a fearsome weapon when given extra burst.
AutoMediKit can be done as a coordinated order allowing multiple Caliban to recover at the same time.
A caliban engineer can bring Slave drones which will allow it to have a wider field of vision and a sacrificial drone to clear mines or make discover rolls. The drone can also be used to engage enemy CC specialists, tying them up for valuable orders.
Because this model has an Auto-Medi-Kit it can be worth taking an extra shot to put them down or at least keeping LoS to them while they are unconscious.
In a mixed fireteam with Sheksiin or Hasht the Caliban will be the weaker link. Try to take them out first before shooting it out with the more deadly personalities.
This profile has the Spawn Embryo rule so when unconscious, it still counts as a scoring unit for scenarios like Quadrant Control or Supremacy. You can bypass this by killing them out right with Shock, Viral, or Mono-filament, or by killing the unconscious models. Shasvastii sectorial players may focus extra attention on your sources of shock. Try to use that to your advantage.
When choosing Caliban you will have to make a decision between two different options: Fireteam, or individuals. Bringing Caliban as a fire team is fairly expensive and is not available infiltration profiles. Furthermore, seed embryos cannot be in a fire team at the start of the game so it is usual worth the extra point to deploy them developed. Corax Hasht and Sheskiin can both be attached to a Caliban team and often this is the best way to make use of Calibans.
Individual Calibans can serve a role of an Engineer or D-charge model for classified objectives, have several infiltrating profiles for mid-field presence, and access to the Feurbach for ranged heavy target cracking. Generally taking a Caliban by them selves works best when trying to fill a very specific niche in the list. The engineer profile can also bring Slave drones allowing for safer Engineering, or the usual tricks of watching the DZ, clearing mines, or engaging a marauding enemy.
Caliban are very expensive models with few defensive tricks. Generally deploy them somewhere that they can accomplish their mission without being exposed to even common ARO. If you wish to deploy them in ARO range, then make sure that they are positioned so that they will be out of LoS when prone. This lets them fail a guts roll if in a shoot out they can't win, dodge to prone, or be out of line of fire when unconscious
Active Turn Role
Caliban are there to complete a mission then engage at close range with the enemy. They are best used with great caution as they lack defensive abilities to keep them in a protracted or unbalanced fight.
In a Fireteam they will most likely be there just to provide orders and link bonuses.
Caliban lack much in the way of defensive tech and should look to avoid ARO when possible. Keep in mind that several profiles have nanopulsers and it may be worth losing the Caliban for a sure hit against camo models.
