I’m hoping to incorporate tau firewarriors into my space marine army by giving them space marine sniper rifles and have them count as scouts with sniper rifles, obviously they would be painted in my space marine colors but I’m not sure if there’s enough fluff to tie them in with my army and explain why firewarriors are fighting with space marines.

I could use some help finding a valid reason for tau to take up arms with space marines

Please help.

Short answer? There isn't one.

Long answer? The Space Marines are proud super-human incarnations of the Imperium's will - a core tenant of which is the mistrust of xenos and their destruction of aliens wherever possible. Unless your Chapter is Excomunicated and/or radical beyond radicality, they would never serve beside an alien.

allright then if they were excommunicate and were on the edge of imperial/tau space and were running low on men supplies and armor then would it work???

[Vash113]

Except in that case Tau would not give valuable men to the Space Marines. No auxilary save Ankhor Prok was allowed to take command of Tau forces and the Tau Empire simply cannot spare any resources.

Either way you look at it, there is just no fluff to support such a thing.

The only thing I can think of is if you filed away the feet and added some sort of boot, and modified the armor so that it could be unique scout/sniper gear. Otherwise... :-\

[Anti11es]

allright though this is something of a conversion question which would be cooler
1. Men at Arms converted to have frag grenades and sniper rifles and some other gear
2. Firewarriors with boots and unhelmeted human heads and sniper gear

so which one of these would work better or ook cooler

[Hive Tyrant Horror]

Maybe the chapter has a radical pysker that is controlling the firewarriors using mind control? Keep in mind that I haven't played 40k in ages so it might be unfluffy.

....could explain it like firewarrior (the PS2 game) they are just working togethor at the time to accomplish the sam/similar goals.

In firewarrio both the space marines and the tau were working alongside each other to rid the world of chaos and destroy the tzeentch greater daemon.
