Our group is playing an Only War campaign, this time as the crew of a Leman Russ. Still in the brainstorm stage, no pen to paper, but just a few things I'd like to discuss.
[1] Which works better for a group with around 3-4 players, playing as the commander of each separate tank in a Squadron? Or as the individual crew of a single tank 'Fury' style?
[2] Should the players get to choose which variant Leman Russ, or is the standard Battle Cannon a solid choice?
[3] How would modifying sponsons and hull weapons work? Can a crew even have them modified for specific missions?
[4] What are some good ideas/events/foes that a Tank focused campaign could include?
[5] If someone wants to play as a tech-priest, how would that work in a front-line scenario?
[6] Should the possibility of a Baneblade prize be dangled in front of them, or is it better to foster love for their own vehicles (Like Knight-Commander Pask)?

The Emperor Protects, but a ceramite hull doesn't hurt.
Cheers.
