Nephew is getting started with Space Marines and he originally wanted a gunline, heavy shooty but strong enough to hold out (not out shooting guard/tau), but enough to put some hurt down.
The real question is, which codex would you use? I was led to Dark Angels, but would love opinions on that. Should he do vanilla marines, dark angels, etc?
For now he'll have a captain, librarian, 2 tact squads, 5 scouts, 5 terminators, a TL razorback, whirlwhind, & land speeder). We can add more as we go, just trying to get a feel of what codex or list you'd run to make a more gunline approach. He'll be using bolter rule too.
