I love the F-bomb. Since you're just starting out, I actually recommend going heavy on the invested points as it saves you money. Are you running unbound or bound armies? I will assume bound, but if not just throw all you got at the bomb. Supporting it is for pansies!
Alright, the bomb is based around a single principle: wargear synergy. What's so incredible about it is the PEN chip, the
MSSS, the CnCN and the
DC as mentioned above. Because they effect the whole unit, and the bomb can grow
big. You put all your systems on one suit, and kit out the rest with target locks to blast away at different targets.
However! That support suit is also the bombs largest weakness. If it gets sniped out, your bomb becomes waaay inefficient for its points. But there is a solution: use a commander. This has three major benefits: 1, your drones become BS5. 2, he has twice the wounds. 3, due to the bomb being bodyguards, you auto pass Look out Sir! tests. You simply cannot lose him without losing the bomb. The commander is CRUCIAL for a strong F-bomb.
The build I use is:
Commander w. Neuroweb System Jammer (awesome for 2 points), CnCN,
MSSS, PEN chip, Drone Controller, Vectored Retro-thrusters. 150pts + 2 Gun Drones 24pts
He provides Hit&Run, Gets hot to an enemy unit, twin-links everything, ignores cover, BS5 to drones, and gives you MH/
TH/Stubborn as preferred each turn. Due to auto-passing
LOS, he needs no defensive kit - when he dies, your bomb is dead anyway.
Another benefit is that you can now have 7 suits with weapons instead of 6. What else do we consider crucial? Farsight, obviously. But a poster above mentioned Shadowsun - she is actually one of the best buffs you can get, beyond the buffmander above. Stealth + shrouded means you get a 4+ cover save in the open, and a 2+ (!) if you have any kind of cover beyond that. Suddenly, your bomb is super-tanky. She also gives you BS5 fusion blasters (although you only get to choose target for one of them, it is still awesome). Now, we're obviously talking about three
HQ slots here, so you would need a second detachment. I usually go with minimum sized fire warriors as troops since the I play the bomb going for the tabling rather than the objective.
Shadowsuns third benefit is also a good one - you do not want to deep strike the bomb, so Farsights warlord trait is useless. Instead, you take her as warlord and get a
3d6 assault move, which is awesome for re-positioning which you want to do a lot - you only get overwatch vs the first charger, so watch out for several units coming at you at once.
Alright then, we got our
HQ:s covered - now we want to add the actual bomb. Due to BS5 drones, all suits want drones. They are also ablative wounds which combined with 2+ cover means it will take a looong time to get to your suits. In addition, you want target locks EVERYWHERE. They separate the bomb from all other deathstars, by being able to fire at almost everything on the board, at once. As for weapon loadout, you want fusion and plasma primarily, however a few missile pods won't hurt as they can target lighter units/transports far away while you obliterate whatever is within 12"-18" of you. Burst cannons are of no use in the bomb, as you will have 32 pulse shots from the drones at
TL BS5. These fire with Farsights plasma rifle and one of Shadosuns fusion blasters on the "main target", and so that unit dies through sheer weight of fire. Here is my recommended build:
3x Bodyguard w. 2 plasma rifles, target lock, 2 gun drones
2x Bodyguard w. 2 fusion blasters, target lock, 2 gun drones
2x Bodyguard w. 2 missile pods, target lock, 2 gun drones
637pts
This is my
TAC build. Depending on your meta, you may wanna change up. Do you see lots of light vehicles rather than heavy? Go 1
FB and 3
MP. Barely any 2+ saves? Take less plasma. The charm is that all three weapons cost the same, so you can swap out freely without adjusting once your list is built. Don't tailor to a specific opponent though, that's no fun.
With points to spare I usually add another commander with plasma rifles and tanky gear to add that extra bit of punch/survivability.
So, this is my preferred bomb list at 1500 points:
Shadowsun 135pts (Warlord)
Farsight 165pts
Commander w. Neuroweb System Jammer (awesome for 2 points), CnCN, MSSS, PEN chip, Drone Controller, Vectored Retro-thrusters. 150pts + 2 Gun Drones 24pts
Commander w. 2 plasma rifles, target lock, Iridium Suit, Stimulant Injector 160pts + Gun Drone 12pts
Bomb:
3x Bodyguard w. 2 plasma rifles, target lock, 2 gun drones
2x Bodyguard w. 2 fusion blasters, target lock, 2 gun drones
2x Bodyguard w. 2 missile pods, target lock, 2 gun drones
637pts
4x 6 Fire Warriors
216pts
Total: 1499 points
Pure. Death.
Broadsides and riptides are both great choices, and they fit well in generic tau armies, so gives you a good core to branch out from later. You could even go for 2 riptides if you're feeling dirty.
