No intentional hijack meant but would appreciate someone much more versed in 40K than my meager noob-lurker status to explain-expoliate something for me.
I see some very cool ground action-engagement vehicles, mostly tanks and troop transports, but not to my knowing seen anything for wet-beachhead type operations.
Not likely every world that the faces an Imperial presence will be dry, so why the absence of a 40K version of a brown water navy or a dedicated 'amphibious' operations branch ?
That said, I return everyone to their regularly scheduled discussions.
