Fortunately not plausible - a RAC20 would soak up 12 crits and 16 tons per. Still plausible, but we're also talking about generating 42 heat per gun when at full rock and roll. Any mech that could handle generating 168 heat per turn and not instantly explode scares the hell out of me no matter what it's armed with.

Maximum Tech. The Rotary AC20 is the cheesiest weapon (at least in my opinion) in a book dedicated to ridiculously cheesy weapons.

Basically, take an R/AC 2, then add a zero to all instances where damage is applied. Can't remember its range: that may be the only saving grace because it's probably short.

I guess I was wrong about it not being in a book! But here's my extrapolation:

--It can shoot up to 6 rounds per turn
--Heat should be like a standard AC/20, 7/shot
--Each additional shot increases chance for gun to jam. It can be unjammed, but I think you can unjam it one turn and then fire the subsequent turn.

It's a murder cannon.

MechForce UK, to be precise. It's nasty. How nasty?

Range 4/8/12, damage 20, heat 7, 16 tons and 10 crits, 5 shots/ton.

BV is 823/118 for weapon/1 ton of ammo. Yes, that means a RAC20 with 7 tons of ammo (about the minimum you'd want for a semi-sustained engagement firing at full rock and roll a few times) comes out to 1650 BV, or more than many Battlemechs.

Of course, if you want even more broken weapons, there's the RAC-10.

The RAC-10 is a mere 7 crits and 14 tons of sheer goddamn bum surprise sex. "But bum surprise sex? How can that be when it does half as much damage?" you say.

Well, it has 6/12/18 range. Yes, the same range as an IS PPC or the LBX-10. It does 10 damage per shot. It generates a mere 3 heat per shot and gets 10 shots of ammo per ton. Firing on 5 shot, on average, it is like having 3 and a half IS PPCs mounted on your mech.

Except those 3.5 PPCs are generating only 15 heat. And given the amount of ammo you need to sustain the gun, you can fire on single shot literally all day.

The best part? As unofficial tech, if you can use RAC-10s you can definitely use CASE II, so ammo explosions are basically a huge joke for you.

It jams the same amount as the RAC 2/5. Firing on 3 shot, it only jams 3% of the time, while firing on 5 shot it only jams 8.3% of the time. on 3-shot you're averaging ~50 damage, while on 5-shot you're averaging 70-80 or so. All you need is to remember that it's your primary gun and you have to baby it a lot.

You do have to make hard design decisions and have good pilots to get good use out of it, sure, but it is also an incredibly ridiculous weapon.

To be fair, the RAC10/20 are totally non-canon and don't technically exist in the BT universe. They're just the wild pipe dream of a fan mag twenty years ago. The actual RAC 2 and 5 are fun tools that have reasonable good and bad points. The bad point is that they do have fairly frequent jams, require a LOT of ammo to function and are rather costly size- and weight-wise for their effects.

The good point is that you are firing six goddamn AC5 shots a round and the world is loving full of dakka. It may not be a Clan ERPPC, but the RAC5 is drat fun.

Given jam rates are in the single-digit percentages and the gun takes 1 turn to unjam, the reduced damage from jamming isn't as meaningful as you'd think on average.

The RAC10 has more range than the RAC5 because it's a Clan weapon. The TacOps Clan Rotary ACs have pretty incredible range actually (although refreshingly, unlike most Clan weapons they mass the same and are larger than the IS ones). Note that the TacOps ones are the RAC2 and RAC5, the RAC10 and 20 didn't make the cut for obvious reasons.

They jam because you're trying to feed about 500 bullets the size of your fist through eight barrels in about 2 seconds, and that means you can get misfeeds because you're trying to do every feed very quickly. A slight misalignment throws the whole thing out of whack and the weapon presumably stops firing instead of blowing itself up trying to jam two bullets down one barrel.

No I'm saying that a 3% jam rate doesn't affect the average damage of a weapon over enough games enough.

If jammed, you don't get to fire for 2 turns as a rough guide, so multiply average damage over time by (0.97)^2 to (0.91)^2 or so to get your actual average damage.

The result is still pretty incredible.

The jam rate is much higher than 3% for shots > 3. Your previous numbers for RAC20 damage are pretty inflated.

I was actually wondering about how they jam rules wise (I thought it was roll a dice for each shot, jam when you roll doubles, but they're fire all X shots for that turn, then jam. This lead to them being weapons you fired once every other turn, since you'd naturally empty all 6 barrels into some poor sucker, then wait a turn whilst the mech cooled down and you unjammed the gun). I remember MW4 Mercs when they introduced these things: The RAC5 was simply a murderous buzzsaw of a gun, that just wouldn't stop pumping out lead. So naturally you grabbed two of them and went to town.

Yeah, it's the computer game. But it did give you a fairly good idea of how monstrous these things were in general.

Much the same as Ultra ACs do.

Normal fire, doesn't jam.
2x fire, and if your to-hit roll is a 2 you jam. 2.77%
4x fire, and you jam on a 2 or 3. 8.33%
6x fire (which you should always be using), and you jam on a 2-4. 16.66%

The RAC was great at punching targets, either twinfired or staggered. Whenever he's cycled and trying to line up some shots with his own PPCs, he's being literally punched in the head and shoulders with explosives. I ended up really learning to love medium and fast-heavy mechs, and took lances of Novas or Bushwhackers on every single solo mission with unified loadouts similar to my own. Carried a NARC, maybe it was a placebo, but it seemed to make my buddies' SRMs hit their mark virtually every time, for a lot of knockdowns at the start of each engagement.

In the various MW4 iterations, I was always a fan of ER Large (for obvious reasons) and Light Gauss Rifles. Why Light Gauss instead of Clan? Well you could fit Light Gauss into a few locations where a Clan Gauss wouldn't fit. But more importantly, 1200 meter range.

Nobody really expects a couple of gauss slugs slamming into their center torso from outside of radar range.

As regards RAC/5s, I once made a custom Turkina that had two cRAC/5s, full Hardened Armor, and more ammunition than god.

It's the kind of 'mech you absolutely have to give to like, a 0/1 pilot, but if you can stay on your legs and keep those cRAC/5s, you'll soon have the other guy decrying "Bullshit!" at his apparent inability to phase you and the way your AC/5 rounds are starting to punch through his armor all over.

Clan RAC-5s have LRM range. If you stay at long range they can just plink you on single shot basically forever.

Of course Hardened armor isn't where it's at. That, my friend, is why the world invented Ferro Lamellor and Reinforced IS. Put that stuff on an assault and you have a tough-as-nails rear end-reaping machine without the piloting and movement penalties of Hardened armor.

And even when you chew through its delicious armor coating, you have the nougaty Reinforced IS which is -1 to all critical rolls and takes half damage. It can even survive a direct head hit from a Clan ER PPC or gauss rifle (15 damage reduced to 12, taking out all armor and 2 points of head IS), meaning the only headcappers against it are AC/20s and heavy gauss rifles.

Hardened Armor still has its uses, even compared to Ferro-Lammelor.

F-L is some great poo poo, don't get me wrong, but Hardened says "TAC? Bwahahaha!" And with the ridiculous tonnage of ammunition in the body of this beast, you'll want the fact that it roffles at TACs.

Granted, it could be a good design with F-L, too, I think. Depends on whether F-L takes up crits. Hardened takes up no crits.

Also, Hardened gives you a lot more staying power than F-L against anything except the other guy spamming light MG boats at you.

F-L takes up 12 crits and is worth every one of them, because it provides virtual immunity against LB-X pellets and basically neuters most critseekers. Basically, any odd-damage weapons get shafted a bunch by how F-L reduces damage, which is pretty nice since quite a few weapons deal odd (non multiple of 5) damage.

It also has the advantage of being significantly lighter and providing more protection per unit weight. (17.5 points per ton assuming you're getting hit by weapons that deal damage in chunks of 5, making it roughly equivalent to a Clan Light Ferro-Fibrous).

Hardened is cool but Ferro-Lamellor is much more general purpose than Hardened armor IMO, since you generally don't sacrifice all that much to put it on a machine.
