"Now, where are my points and capabilities...you're going to have to work harder than just do the happy dance for your sentinels." Are you suffering from heat stroke, South Texas? I sent them to you two emails ago and you commented on them. I really don't know what to revise them to at this point, however, since you are waffling on what to do with the unit. One shot, two shots, BP shot... That is a big spread. I am fine with either the first or the second iteration. BP weapons make me think it will be too much, but I suppose one of the Support Sentinel configurations used to be a rocket pod. The question is what would it be closer to in terms of firepower.
Twin Typhoons are AP3+/AT5+ at 45cm, not indirect. One of those would be 45cm, AP4+/AT6+, direct fire, and that isn't a bad stat line for comparison.
Whirlwinds are 45cm 1 BP Indirect. That IMO would be too much. Cutting it in half would get weird in a hurry too.
Valkyrie Rocket Pods are 30cm 1 BP Disrupt, but those are also one-shots. I don't think this army needs any more 1-shot weapons to be honest. Or BP weapons either.
Here is the Lexicanum breakdown on them...
The Missile Sentinel is armed with a missile launcher and is designed for multiple roles including both tank and infantry hunting.
The Rocket Sentinel is armed with a Multiple Rocket Pod and is designed for a similar role to the Missile Sentinel, just without so much range and destructive capability.
Multiple Rocket Pods are a rapid-fire launcher loaded with standard Frag Missiles but with a faster rate of fire.
Missile Launchers mounted on Sentinels are designed to fire indirectly, however they still fire standard Frag and Krak Missiles.
Reference:
http://wh40k.lexicanum.com/wiki/Multipl ... _Launchers Frag Missiles are designed to explode on impact with any surface, raking the immediate area with lethal shrapnel. Primarily an anti-infantry weapon, it can be used against light vehicles with some success. Frag Missiles are often ineffective against heavy infantry.
Krak Missiles are primarily designed as anti-vehicle weapons, Krak Missiles contain a high strength, low blast shaped charge, causing massive damage to anything it hits with minimal collateral damage. Also very effective against heavy infantry, bunkers and other armored targets.
The standard Imperial Missile Launcher has a built in targeting device and is fired from the shoulder. It is a single round weapon, and cannot be fired on the move. Standard Imperial Guard doctrine is for one man to carry aim and fire the missile launcher, whilst a second man carries the ammunition and re-loads the weapons. A well-drilled fire team can maintain a formidable rate of fire, enough to daunt the bravest of tank commanders. Space Marines generally carry their own ammunition, being easily strong enough to hold the missile launcher in one hand whilst re-loading with the other. Note also that whilst an Imperial guardsman will generally fire from a kneeling or prone position, Space Marine enhancements grant them a superior aim even from standing.
So that is everything I could find on their weaponry. Missile launchers were definitely designed to "fire indirectly", so a 45cm AP5+/AT6+, indirect would be in line with that. If left as is, that would mean a range of 90cm. I am going to back-peddle a little here and propose that maybe that isn't a bad idea after all. Really, besides Vultures with their one-shots, what has any range in the Elysian army? Nothing. It isn't like the Support Sentinels are overpowered, over overarmed, overarmored. If it is the same weapon AND designed to be fired indirectly, then that is the by-the-book stat line.
If you can't stomach the idea of a 90cm weapon range (even if it is indirect), then IMO the next best thing is to put in a lower range of 30cm-40cm. Doubling it puts it at 60-80cm indirect range and that is totally workable. It also avoids any special rule which is preferable. Lastly, it helps the formation fit well as an add-on to the Mortars which already have an indirect range of 60cm.
Mortar units + Support Sentinels upgrade
Drop units + Drop Sentinels upgrade
Drop Sentinels as an independent formation
Support Sentinels as an independent formation
Yin & Yang. Balance in design. All is right with the world.
Anyway, that is all I have for you. Run, Forrest! Run!!!
