Since I have now had the opportunity to have a few solid games of the new edition I would like to bounce the issue of kitting out sergeants and ICs off you fine people.
With the introduction of 'challenges' we can no longer rely on the 'hidden Powerfist' to get our units out of tight scrapes. I do not consider any Space Marine turning down a challenge at all fluffy. Lets face it; Tactical Squads rely on their Sergeant to do the heavy lifting in a combat against all but the weakest of combat units. (Please no "Well durr, just stay out of combat then..." comments. They are not helpful.)
I'm fairly confident that if you have a 2+ save like with Honour Guard then it's the safest bet to take an AP 2 weapon like a Power Axe or a Thunderhammer on your Champion / Sergeant as you are likely(?! lol) to survive anything attacking before you (monstrous creatures, Dreadnoughts etc excluded of course but then you'll just be being nailed in initiative order anyways).
I am also confident that if you are planning on attaching an IC to the unit that either the IC or the Sergeant should have an AP 2 weapon and the other specifically not so as to be able to have a choice as to who declares / accepts a challenge depending on what they might find themselves in combat with.
An example would be a Captain on a Bike (S10 to instagib him - T5) with T/Hammer, S/Shield + Artificer Armour (2+ 3++) then you're Bike Sergeant / Company Champion should have some manner of Power Weapon in order to strike in initiative order. But then would you take a Power Maul, lance or Sword? Ok in this instance you might be tempted to take a Power Lance but I would like to keep the discussion more general than this.
How do you kit out your Sergeants and why?
