No, the positioning of the Firewarriors to the Devilfish is not what's important, they don't stand under it. Picture this:mephistophales said:
Your opponent can only charge if they are within 6".
Your opponent can't move within 1" of one of your models (i.e. the Devilfish).
If you position the Devilfish in front of your squad at the correct distance, the detour your opponent must take means the distance he must move to go all the way around the Devilfish is such that you are out of charge range. There are more exact measurements and nuances to it, but that's the underlying principle.

See Tau Codex page 17. A Crisis Suit hardpoint is for Weapons or Support Systems. Putting 3 weapons on a load of your Crisis is usually a bad idea, as even with a multi-tracker you can only fire 2, and you don't have the hardpoint to take the multi-tracker anyway (remember not all units can take Hard-wired systems).mephistophales said:
