Details on how Legion Tactical squads are working in the Horus Heresy Book 1 Betrayal. They definitely are rather cheap with 10pts each for additional marines with a lot of upgrade options. So take a look at the bulk of your troop forces for the new release.

9 Marines/1 Sergeant
Wargear:
Power Armor
Bolter
Bolt Pistol
Frag and Krak Grenades

Options:
Add up to 10 additional Legion Space marines (10 pts each)
The entire tactical squad can do ONE one the following:
- Exchange their bolter for a combat blade or chainsword (Free)
- Take an additional combat blade or chainsword (2 pts per model)
One marine can take a Nuncio-vox (10 pts)
One marine may carry a Legion Vexilla (10 pts)
The Legion’s sergeant may exchange their bolter for one of the following (this seems like an oversight because if the squad switches to being an assault marine it means that you can’t upgrade the sergeant)
- combi weapon (10 pts)
- plasma pistol (15 pts)
- heavy chainsword (5 pts)
- power weapon (10 pts)
- power fist or single lightning claw (15 pts)
The sergeant may take melta bombs (5 pts)
The sergeant can upgrade to artificer armor (10 pts)
Fury of the Legion:
While at least five models remain in the unit armed with bolters, or bolt pistols, the squad can elect to make a Fury of the Legion attack in the Shooting phase so long as they did not move, arrive via deepstrike or disembark rom a vehicle earlier in the player turn. Models making a fury of the legion attack may fire twice with their bolters or bolt pistols against a single target (note that in the case of a combi-weapon, only the bolter part may fire twice).
Owing to the massive expenditure of ammunition involved, once a squad has made a fury of the Legion attack it may not use Overwatch fire later that turn or fire in the shooting phase of their next player turn. Fury of the legion may not be used for snap shots and models joining the unit do not benefit from this rule and must fire normally as does any non-bolter weapon used by the squad at the same time as the Fury of the Legion attack is made.
