Lemartes

While this model is leading a unit, each time an attack is allocated to a model in that unit, subtract 1 from the Damage characteristic of that attack.

While this model is leading a unit, melee weapons equipped by models in that unit have the [LETHAL HITS] ability.

This model can be attached to the following unit:

■ Death Company Marines with Jump Packs

If your Army Faction is Adeptus Astartes, at the start of your Command phase, select one unit from your opponent’s army. Until the start of your next Command phase, that enemy unit is your Oath of Moment target. Each time a model with this ability makes an attack that targets your Oath of Moment target: ■ You can reroll the Hit roll ■ If you are using a Codex: Space Marines Detachment and your army does not include one or more units with the Blood Angels, Dark Angels, Deathwatch or Space Wolves keywords, add 1 to the Wound roll as well.

Each time this unit makes an ingress move (20.04), if every model in this unit has this ability, it can be set up anywhere on the battlefield that is more than 8" horizontally from all enemy units, even if that is within your opponent’s deployment zone.

This ability always takes the form Feel No Pain X+. Each time a model with this ability would lose a wound, roll one D6: on an X+, that wound is not lost. 

Each time an attack made with a [LETHAL HITS] weapon results in a critical hit, you can choose for that attack to automatically wound the target.  Designer’s Note:* Choosing to automatically wound the target means that no wound roll is made for that attack. You may decide against this, as it means that attack cannot result in a critical wound* and so cannot trigger other abilities such as [DEVASTATING WOUNDS].
