A Question of Sorts

While attending a Convention a few weeks ago, I was asked how I would go about makeing a standard space marine army that has the best ability to put long range fire power down the field.

Since Space marines are notorious for short ranged weapons, I had to give it a bit of thought, but this is what I've come up with.

SLOT	Unit	Upgrades				Army Total
HQ	Master of the Forge					1980
		Conversion Beamer
Elite	Dreadnought
		Twin Linked Autocannon
		Twin Linked Autocannon
	Dreadnought
		Twin Linked Autocannon
		Twin Linked Autocannon
	Dreadnought
		Twin Linked Autocannon
		Twin Linked Autocannon
Troops	Scout Squad	Unit of 10
		Sniper Rifles - 8
		Heavy Bolter (w/Hellfire)
		Sergent Telion
Troops	Scout Squad	Unit of 10
		Sniper Rifles - 9
		Heavy Bolter (w/ Hellfire)
Fast Attack	Land Speeder Squadron	Squadron of 3
		Multi- Melta
		Heavy Bolter x2
		Typhoon x3
Fast Attack	Land Speeder Squadron	Squadron of 3
		Multi Melta
		Heavy Bolter x2
		Typhoon x3
Fast Attack	Land Speeder Squadron	Squadron of 3
		Multi-Melta
		Heavy Bolter x2
		Typhoon x3
Heavy Support	Dreadnought
		Twin Linked Autocannon
		Twin Linked Autocannon
Heavy Support	Predator
		Autocannon
		Heavy Bolter Sponsons
Heavy Support	Predator
		Autocannon
		Heavy Bolter Sponsons

Now, i know it seems dreadfully short on most of the staples of a Standard SM force, but consider.

The scouts deploy on/near a ruin that has been bolstered by the MoF (3+ cover, 4+ armor)
and put down a LOT of Sniper Fire up to 36" away.

The 4 Dreads put out 16 Twin Linked S7 shots per turn.
The Preds add another 4 S7 and if still can add another 12 S5

The Heavy Hitters are the land speeders though.
They drop out a total of 18 S8 AP3 shots AND 18 S5 AP4 Shots AND 3 S8 AP1 Melta shots PER TURN.


and the MoF sits with the Scouts (squad not Telions) and can help or just add a blast template to their fire.

What would you make to do a Long Range Firepower list with Space Marines?

What are your thoughts?
