It's a return to the U20 squad for Mills who has been required for Gloucester first team duty for Gloucester in the past few weeks whereas Britton and Robson have been plying their trade in the white shirt of England.
It's three from three thus far for Rob Hunter's side but talking to the Gloucester Citizen this week at the final media session before travelling to France, the Gloucester contingent are aware that this weekend's game is 'Le Crunch'.
As Mills explained:
"France in France is about as big as it gets in the Six Nations, and we know we've got a huge job on our hands to go over there and get a result.
"We haven't looked beyond this game, that might sound boring but it's true, because this is huge for us and will be a big, big test."
"France are such a switch-on, switch-off side that you just never know which version of them will turn up.
"But even if they start slowly and struggle, they can flick that switch at any point. They have always been like that at senior level but they are the same at this age-group too.
"But we can't try to second-guess them, we just have to prepare for their best-possible performance.
"At home in front of a pretty feisty crowd as well, it's going to be a massive atmosphere, but we can handle that."
And Robson confirmed that nothing is being left to chance:
"Last week in Italy we won with a decent scoreline, but the performance was not where we wanted it to be.
"So we have worked very hard this week, just on tightening up the screws, because we know we'll be under pressure from France.
"It's encouraging we can win without playing to our potential, but we know that this week especially we've got to get our game spot-on.
"It's a hugely exciting test and we can't wait, but we know we've got to improve to handle the French."
