Advisors are, generaly, a good choice to throw into a command squad. Lets go in order from the codex.
Sanctioned Psykers: Here, well, you get what you pay for. Its a cheap unit that can either get you an okay ability or will be entirely useless. It is very random at what ability you could get, so you may not get what your looking for. Abilitys like Telepathic order is what you are shooting for, as well as psychic ward. Any other ability is mediocre at best. The only time id use them is if I have enough extra points to fit one with the honorifica and its force weapon.
Commissars: A very nice unit. Will boost the squads leadership he is attached with an extra point. This affects the leadership 12" ability. Great to keep the men in line. Though, if the Commander fails his own leadership test for falling back, the commissar initiates summary execution. Your commander is dead, and the commissar takes charge, and they never fall back. Give the Officer a trademark item, and the command will never fail morale cheaks. If you have a psyker in the group, the commissar will execute him if he falls to a perils of the warp. Take note that the Leadership bonus does not transfer through the vox network, so if you have vox's, better to leave the commissar at home.
Priests: They are great at bolstering the assaulting power of the squad. I would definatly throw them into my command squads and platoon command. It turns the group into awesome close comabt monsters. Definatly a great counter assault unit. The fanatical ability well make shure you hit your enemy. Because of righteous fury, your squad will have to assault anything in range of them, so you may have to be a bit tactfull on were you place them. This also means you cannont use a heavy weapon in that squad. Rosarius gives the priest an invernerable save, but it is expensive. Id do it only if you have enough points in the end. Holy relic will give any troops in the area of affect a bonus attack in assault. It is hard to set up and to find the right time to use it, but when you get it right, your enemy will feel it. Also expensive. |
