I propose an Alexandre Dumas shipment for the french.
Alexandre Dumas was a french writer who wrote many books, the most famous are the The Three Musketeers who feature the adventure of Athos, Portos, Aramis and D’Artagnan.
So this shipment consist of : book of experience and 4 royal musketeers. Upgrade all your existing royal musketeers to royal guard.
I just watched the 1977 version of The Man in the Iron Mask last night! So yes, an Alexander Dumas shipment would be really cool!
Maybe said shipment can be sent three times to reflect the fact that there was a Three Musketeers trilogy.
There allready is, fencing school for the French now also sends 3 royal musketeers. That doesnt seem to be just some random number.
