And the WRU want the nation to wear their Wales shirts, or anything red, to work this week and ensure a sea of red wherever you look in Cardiff, or around the world, come match-day.
Using social media channels or by emailing firstname.lastname@example.org fans are being asked to take pictures of themselves wearing the red of Wales and record film clips which correspond to the WRU's 'we are one' campaign (available on youtube ) aims to show the players that the nation is united in its support of their bid for championship glory.
The union has also set up a unique email address and is calling on Wales fans around the globe to fill its inbox with messages, videos and pictures which will be edited and presented to the players themselves to inspire them on match-day.
Wales wing sensation (picture attached) George North has welcomed the campaign and reiterates the importance of a strong fan base to our international heroes.
"Everyone talks about the positive impact the crowd can have on the pitch because it is true," said North speaking today from the national squad's training camp at the WRU National Centre of Excellence, Vale Resort Hensol.
"It makes such a difference the players to be able to hear your home fans in full voice on a match day.
"We know going into every game that we have hundreds of thousands of fans behind us, we know we have the best fans in the world game in Wales.
"Looking up to a sea of red in the stands on Saturday or catching site of the good luck messages sent to us via social media or from our friends and family is an inspiration and we are all looking forward to taking that out on the pitch at the weekend."
WRU chief executive Roger Lewis said:"The unity of purpose displayed by our national team during this campaign has been uplifting and inspiring.
"This strength of character has been recognised by the whole country and has been totally supported by the 314 clubs which make up the Welsh Rugby Union and the fans at large.
"Our small size is our strength and to achieve all that we desire we have to continually be smart and innovative.
"This show of unity from our fans, if they can come together and show the players what they mean to them by wearing the red of Wales, can have a direct impact not only on proceedings on matchday but will show the world just why it is so wonderful to be Welsh."
