The large template is huge. I think I'd just save that for the orbital barrages (or use instead of 3 templates possibly).

It's not that big. About 3 times the area of the small template, but remember that when placing multiple small templates you can actually hit more targets than with just a single large template, due to edge effects and choice of placement. The large template actually constricts your targetting min-maxing, and it's easier to use than placing multiple templates.

Besides the idea is that the to hit numbers are adjusted appropriately. Certainly far more elegant than multiple templates with different to hit numbers.

I like the idea of being able to exchange the small for the large template.

Maybe with minuses to-hit?

Well that's the effect tried to achieve in my two tables on the previous page. Actual numbers that work well take a bit of figuring out and playtesting.

I kind of like the idea of using the larger template.

I?ve crunched some numbers for a Concentrated/Dispersed Barrage Idea. As I said on the previous page this was done with 4 objectives in mind:

1. The epic rules are designed to use the template sizes sold by GW. You get 1 of each... shame to not use that big one more, which would be easier than putting down additional templates.
2. Epic rules are more realistic and complicated than 40k, but they do not get into the level of detail that your average modern warfare rules-set does. It would be wrong to introduce too many details to consider each time you fire a barrage (except as optional house rules).
3. Some variety in artillery sheaf types would nonetheless be a nice addition and interesting. For example depending on whether you are targeting titan or a dispersed infantry formation it would be nice to concentrate or disperse your fire respectively.
4. As much as possible, increases in fire effectiveness should increase gradually in a linear, but plateauing fashion, rather than the sudden jumps that occur in the present table.



Comparison of relative casualty rates between different Concentrated/Dispersed Barrage Tables and the standard EA Barrage Table were estimated by placing templates over a grid of 2cm wide by 3cm deep squares (each square containing a rhino). The total grid contained 48 rhinos placed 12 wide and 4 deep (obviously not a likely formation but just done for stats purposes). I fiddled with the numbers in Excel to get comparable results with the current EA barrage system. However, note that for very narrow formations the standard EA barrage Table will be more deadly than this Concentrated/Dispersed Barrage Table (and the converse is true but only marginally). Cover and Sustained fire effects were also examined.

To use this system you decide to fire either a Concentrated Barrage (Small or 'Sm' in table) or a Dispersed Barrage (Large or 'Lg' in table). For a Concentrated Barrages you place one small template. For a Dispersed Barrage you place one large template. Numbers needed to hit targets under the template are shown in the Table below. *?s indicate the number of extra BM to place. NA means that firing option is not allowed.



BP?s    SmAP     LgAP     SmAT     LgAT
1           6           NA         7            NA
2           5           NA         6            NA
3           4           6           5            7
4-5        4*         5           5*          6
6-7        4**       4           5**        5
8-9        4***     4*          5***      5*
10-12    NA         4**       NA          5**
13-15    NA         4***     NA          5***
16-18    NA         4****    NA          5****


This Concentrated/Dispersed table produces the same number of casualties as the standard EA Barrage Table but fixes the broken 4-5 and 6-7 range brackets (there is a gradual increase from 3 to 4-5 and then from 4-5 to 6-7). However it also levels off the casualties at the 6-7 range rather than the 8-9 range (and further increases in damage are then just in numbers blast markers placed).  Justification for the early levelling off is threefold:
- The alternative would be to increase ?to hit? numbers to 3?s for infantry and 4?s for vehicles which I think is probably too powerful for artillery effects against these classes (? ? if not then the same casualty rates can be maintained).
- I judged it more important to fix the broken lower range brackets that are frequently used, than to exactly duplicate the amount of damage at high levels of BP?s that are infrequently used.
- In any case, the casualty rates I estimated for high BP attacks in the standard EA Barrage system are perhaps overestimates for practical purposes, given the  target dimensions they require.

I also took the opportunity to make the low level AT attack a 7 rather than a 6 to maintain proportional damage of attacks, but this could be thrown out for style reasons.

Also Concentrated vs Dispersed fire should perhaps be called ?Converged? vs ?Distributed? to conform to real world military lingo.


For Orbital barrages a Concentrated and Dispersed Barrages both use a single large template. However a Dispersed Barrage also targets any units which are within a small templates distance of the edge of the large template. This is close enough to the effects of the current system though once again not as good against narrow targets.

So rip it to pieces... :)
