I think to use the Storm you need to think like a Scout Sergent... how would you use it, if all the force you had available was your Scout squad?
As I understand it, Scouts have two primary missions:
1) Scout ahead and grab an area to be reinforced later, if needed.
2) Defend a rear objective while providing sniper support.
The Storm is the perfect vehicle to support these roles. It can sit back and defend the rear deployed scouts from deep strikers, while providing an assault vehicle for counter strike, or retreat. Or, it can be used agressively to take forward areas.
A ten man Scout Squad can contain a variety of scout types which can be divided into two combat squads as needs dictate, depending on the role the scouts are to play. One such unit might be composed of a Sergent with power fist and combi-melta (assuming he can have it,) four bolters, a heavy bolter, and four snipers.
The unit can deploy as one unit, if needed, defending an important objective. Or, more likely, split into two combat squads.
The heavy bolter (Hell Fire rounds as per Tyranic War Vets) and/or sargent (maybe Telion for better targeting) can be left with the snipers. Or, can deploy with the bolters as desired.
A Scout Combined Arms Tactic:
The bolters deploy in the speeder and the speeder moves 12-18" to within 12" of the enemy. The bolter scouts remain loaded in the speeder to protect them from assaults, or deploy to cover if posible. If the scouts are deployed, the speeder should be placed to provide a hard to hit speed bump to deter possible enemy assaults.
The bolter scouts rapid fire on the enemy, (if Telion is with them, he could possibly pin the enemy.) Then the snipers fire, possibly pinning the enemy, (if Telion is with them, one sniper scout or the heavy bolter with Hell Fire has a better chance of hitting.)
Next turn, if the enemy is pinned, the bolter scouts can move to within 6" of the enemy and rapid fire them, while preventing the enemy from doing anything but going to ground (no chance to rally because the scouts are within 6".)
The scouts can then assault the enemy, if the enemy has not been pinned, has been whittled down enough, or the area must be immediately taken. The bolter scouts can shoot with pistols first, before assaulting. If assaulting out of the Storm and the enemy lost close combat, they must subtract a further -2 to leadership from the Storm's mind weapon.
If the Storm has a gun type weapon (Like a Storm Bolter, get the pun...?), it can aide in the attack while detering enemy deepstriking reinforcements. Or, it can be used to make a hasty redeployment or retreat. The Storm can go back to the snipers and do the same for them.
Depending on how well pinning works, and/or how many close combat wounds are needed, Scouts can vary thier weapons to adjust.
Another idea might be to deploy the snipers in the Storm, while the bolter troops deploy forward. The Storm remains stationary the first turn, allowing the snipers to support, then rushes forward to allow the snipers to support the assault (if the Storm allows assaults out of it like a Land Raider?) Lots of different weapons types would work well here...
But, I don't have the new rule book yet, so I maybe be off with some of my ideas...
