I've tried looking up but could not decide where I should post this. Its not pertaining to DMs and Rules, nor art nor fiction so I figured thought it may be alright to post here. My apologies if I have gotten it wrong.
Would like to seek advice on how to deal with a squad leader who tends to run off by himself when he likes it. In game my kill team member claims that his character plays to his demeanor of staying on the hunt even though others may give up. The other members just seem to buy it.
I'm currently playing a Ultramarine Deathwatch Librarian. My squad currently consists of a Blood Angel Assault Marine, a Space Wolf Techmarine Iron Priest, a Storm Warden Devastator, and a Dark Angel Apothecary.
Personally my character's beef with this is (being an Brainy Smurf is):
i) A squad leader is first amongst equals. He should strive to be exemplary to lead the team. He ran off in a battle to chase an enemy leader unit without knowing the number of enemy. Leaving three members behind and one injured storm warden bounding after him. This is reckless, unbecoming of a marine and non codex (fluff wise I referred to Graham McNeill's novel Honour and Glory).
ii) Even though he is able to complete an objective by himself, it was an impetuous act which nonetheless endangers the kill team.
iii) GM gives free rein to players to roleplay.
In light of this, what actions would you recommend my character take? Personally I think this behaviour should not go unpunished. As second in command of the team, my character is motivated to relieve him of command and to report this matter back to the DW once this is over. I could try to counsel the character and chide his actions but that is being too merciful and would encourage his behaviour further.
How would you advice me to approach the scenario. Thanks for your input.
