All Combined Army Spec Ops have access to the usual list of weapon upgrades along with some unique high powered weapons for the Combined Army. This includes access to a Monofilment CCW for 2 points and a Plasma Rifle, a particularly nasty weapon in a fireteam
Corax: this trooper comes standard with a Pistol, Knife, and Combi rifles with light shotguns, the latter offering a +6 within 8" and a template makes them dangerous at close quarters and somewhat negates a poor base BS.
Corax: Seed-Embryo is an imperfect rule, but it still offers some defense for this trooper. They will start the game in Camo and at Silhouette of 0 meaning that they are easily hidden and any attacker who wants to get to the back field at the very least has to discover them or use a long skill intuitive attack before clearing them. This profile has the Spawn Embryo rule. Spawn Embryo mean that 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 might consider taking out enemy units with Shock, Viral, or Monofilament as a higher priority to exploit this rule.
Corax: Somewhat corner case, but Seeds begin at a Silhouette of 0, but once hatching are immediately placed standing. This means that they can surprise an unwary opponent by being in ARO position without having to spend an order to stand up.
It is also possible to take other seed-embryo models (Corax Hasht, or Caliban profiles) and take advantage of the fact that your opponent likely thinks they are just seed soldiers. This could be a way to make it appear there are more points "off board" than their really are.
Corax: A Corax in Seed-Embryo state is very vulnerable. While it might seem nice to jump AD in and kill them while they can't respond, remember that the Shasvasti player likely has an ARO (visible or hidden) guarding them. It would seem like Speculative Fire would be a good option here but be sure to consider your chances. Firing at a 4 to hit is low odds AND grants the seed ARO which they can use to hatch, expanding their options on subsequent orders. That said, they are still one of the more vulnerable parts of a list and killing them depletes your opponent of valuable orders or special options.
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 players may focus extra attention on your sources of shock. Try to use that to your advantage.
Corax: Given the low combat stats of the baseline trooper a Corax is best employed as a specialist. Access to an EI hacking device (especially valuable in the Shasvastii Sectorial), Doctor (at a lower price than the MedTech), or Engineer on a base WIP 13 profile is very desirable. While it is possible to craft a Corax for direct combat, the low starting CC and PH means you will spend much of your points just getting up the basic trooper levels. You also lack fire team access. All this said, the Combined Army Q-drones love a Corax Hacker Engineer to buff their shooting and repair them when they go down.
Corax: This model is deployed in the Seed-Embryo state. This means that:
1: They are a Camo Marker 2: They are a S0 Marker 3: They cannot be placed prone
This makes it plainly obvious to your opponent which camo markers are Seeds and which are not, so it is not useful as a "shell-game" tactic to hide your other troops.
A Seed hatches when:
1: at the start of your second turn if you went first. 2: at the start of your first turn if you went second. 3: when it uses the ARO/Short Skill "Hatch"
SPECIAL NOTE: remember that when they Hatch Corax are placed STANDING. This may mean that they are in LoF when they had previously been safe.
Active Turn Role
Corax: Without a link to increase your effectiveness you will be limited to solo roles and very dependent on your XP cap. With a low XP cap the Corax can serve as a good Doctor, bringing potentially higher WIP than the MedTech and adding on either other specialist roles (Hacker or Engineer) to assure you can complete your classified objectives, or some defesive skills like Mimetism.
Corax: While in Seed Embryo state the seeds are limited to "Hatch" as an ARO. doing so means they are probably taking a shot in the face, so consider carefully if it is worth using this ARO an revealing yourself. Even at 8" most discover rolls are only a 50% chance of success and failure means the same troop cannot try again that turn.
A special note on the EI Hacking Device profile, it appears given rules as written that you will be granted ARO when an enemy Hackable Model moves within your Hacking Area. This could allow a Corax to emerge early, but choosing to reveal yourself this way may have consequences if your enemy was a hacker themselves who can now target you.
Once hatched Corax are like any other budget line trooper. Their light shot gun is nice at close quarters or for clustered foes, and in suppressing fire they can be a pain by weight of numbers. Dodge is generally a poor option given your PH stat of 9, but there are cases where it is warranted.
