All ships must organise thier weapons into batteries. Yes, already acknowledged & assumed in the rules. In order to get a battery USP, batteries are formed of from 1 to 30 weapons.
Matt this is where you get it wrong, friend. A battery is NOT 1 to 30 weapons.
A battery is from 1 single turret to 10 triple turrets. Looks the same, but is not functionally the same.
The remainder is a wordier rephrase of the mixed turret rule, which already states in relation to mixed turrets "each weapon is a battery", effectively preventing the abuse the errata is concerned about (ie: batteries formed of mixed turrets).
However it doesn't address whether the first two sentances of the Batteries section, are refering to weapons or turrets.
- If refering to weapons, it considers a weapon to be the minimum battery size (as Book 2 does) and allows a turret to have three weapons of the same type as three batteries (which is NOT a mixed turret and is the norm for book 2 ships). The 'mixed turret rule' merely demonstrates that under Book 5, a single turret clearly has the ability to operate multiple batteries.
- If refering to turrets, it considers turrets to be the minimum battery size, but throws up the problem that more than 10 turrets 'of a type' must be grouped. More than 10 turrets 'of a type' and you cannot have single turret batteries. The 'mixed turret rule' is interpreted (by Dean et al) as an exception to the rule that proves the rule.
First of all, Matt, you are again confusing that you must group "more than 10 weapons of a type" with the fact that a battery CAN be from 1 to 10 turrets.
Whether you think '"mount=weapon" or "mount=turret" you are making a factual error there.
There is NOTHING in there that says you must group more than 10 weapons of a type into groups of 10.
It says if you have 11+ weapons, you gotta group them. AND, if you group them, they GOTTA be in turret sized amounts. And the Smallest turret sized amount is 1- single turret. And that the MOST you can group them into is ten triple turrets, AKA a 30 weapon battery.
OK, so to lend a little illustration to what I think Matt is saying, under his "Weapon = mount" idea, THIS is how it would work:
So if you have as few as 11 lasers in as few as 4 (triple) turrets, then he thinks that the rules are telling him he must group these 10 lasers in a battery. But because that 11th laser in in a triple turret he thinks that somehow it matters that now he has to group these 11+ lasers into a battery (because he thinks "mount=weapon").
I say, OK, then group them. But Matt, that just means that your smallest battery is still ONE turret, and since (in this hypothetical case) you have 4 of them, you can do EITHER 4 - 1 turret batteries, 2 - 2 turret batteries, or 1 - 4 turret batteries. Because the rules state they must have the same USP, all the turrets have to be full, so you actually have 12 lasers in total, 3 in each, to be legal.
But all this line of reasoning does for you Matt is force you to group your batteries before you wound "need" to do so under "turret=mount", SO now your largest ship possible for use in Book 2 is 400 tons, in this kind of case.
And we all I think share the understanding that the intent is to allow ships up to 1000 tons to be backwards compatible, so this is not consistent with that idea.
If Don you are leaning toward Mount = Turret, we now need the issue of what is a turret 'type' cleared up.
Dean pointing to a sentance which in effect states a battery may be of 1 to 10 turrets does not over-rule the phrase "more than ten [turrets] of the same type must be grouped".
No it doesn't. But neither does that sentence LIMIT the grouping to groups of 10, as you seem to think. IF I have 11 identical turrets I can group them any way I want SO LONG AS each group has the same USP, and there are between 1 and 10 turrets in each battery group.
What is true is that prime numbers like 11 will force you to make 11 single turret batteries (because it is not divisible).
12 turrets could be 12 batteries, 6 batteries, 4 batteries, or 3 batteries, or 2 batteries (edit). All of these are between 1 turret and 10 turrets in size, so are legal.
Which is why the example talks about "Optimal" configurations, because some groupings "waste" your firepower in those dead spots between the USP codes reflected on the turret weapons table.
