This is a great video to pair with the box and handed to new players. Explains certain things very well.

3:48 I genuinely LOVE that shot.

A small thing that I see as making a big difference is that most of the models are M 6-2 rather than 4-4. Those extra two inches are going to make a major difference when it comes to order efficiency. There are also several Orders and Order combos that they can get more out of. Dodge in their active turn only means giving up 1/3 of their movement rather than 1/2 so, they can move further before they have to stop. A Cautious Move of 6" instead of 4" is huge as it makes them a lot more able to get around without getting shot at. That they also seem to be quite liberal with Stealth means that you can more quickly get models into positions that are quite vulnerable. A Silverstart Rover can on three Move-Shoot Orders advance 24" on four Orders while a model with only 4-4 is limited to 16". To move the same distance it would take six Orders. For a Faction that relies on HI this is quite Order efficient even baring their Tactical Awareness and NCO.

It’s more than the helmet and the colour scheme. The Aquila on the chest and the shoulder armour definitely look like Space Marines. The Ultramarines colour scheme doesn’t help any. I’m not mad about it, I think they look okay. Awesome video, I like the profile breakdown. I hadn’t realized how badly they were lacking hacker options.
