I am in the process of building a 'farsight bomb' list for tau so lots of crisis suits are being purchased and converted into body guard crisis suits as farsight can have up to 7 body guards ! The norm is 1-2 to protect a commander lol admitedly their is alot less heavy support in a farsight army and no outflanking kroot to help out but I just love the fluff for him and the model i built and painted to represent him on the table is kinda cool in my opinion.

However it is always fun to have more than one list so I am building a second list with even less ability but I couldn't resist the urge to make my own ethereal with fire warrior veteran bodyguards ( ten of them all with one higher than normal BS making them BS 4!) This would bubble wrap the ethereal who has no armour save but the honour blade he weilds adds plus 2 strength and he has ws4 and 4 attacks on the charge. This is still a very poor unit for close combat thou but a fearless unit now with the etheral in it and lots of accurate strenght five pulse shots will do lots of damage.
This higher balistic skill means they won't need to rely so much on marker lights so these can be used to reduce cover instead or be used for other units to benefit from instead.
