still and often be at a safe distance to do well, whereas melta guns must be very close to the enemy to do any good. Having them both in the same squad means one isn't going to be used. It may be a better idea to make the squads larger and split the duties of the weapons evenly. One squad with a meltagun and multimelta while another has a missile launcher and perhaps a plasma gun? It's generally accepted that two 10-man marine squads is what most people should run, no more or less. Marines are a bit overcosted for minimal offensive power, but have the staying power to stick to objectives a bit better. More than two squads is spending tons of points on a unit that doesn't offensively do much of anything with anything to anything. Less means that your objective holders are going to be too few or too squishy and will be destroyed at the slightest whim. So mayhap two 10 man squads might be more fitting for you. Most people don't like captains, nor command squads. Personally, in a 1k point army, I think they're fine. I have had a captain with a thunder hammer and a slightly souped-up command squad take down a full squad of Eldar Striking Scorpions with their phoenix lord, in no small part due to the company banner. The command squad's upgrades are a bit pricey though so I'd stick with the banner and maybe the champion (like you have).
