How about the granatbuchse39 as a kit? With High explosive and Anti-tank rounds. We do have the Brit riflenade kit already, so why not give the Germans a cool grenade kit of some sorts.
oh, i forgot to add that I really like the idea of musicians (especially a bagpiper), it would be cool to have the instrument work as a morale or health tool. It would be so cool to hear a piper in the distance playing a wee tune and to have anyone who is close enough to the piper get totally healed or have his stamina bar fully boosted. (the stamina idea I really like)
A british or Canadian Bagpiper's kit could have:
1) a Dirk (which is a short sword, or long ass knife depending on definition of its' use)
2) Lee Enfield No.4
3) Bagpipes
for the Germans, I propose some sort of Oom- Pa- Pa Brass instrument like a tuba
for Russians, a guitar or balalaika
for Japanese, a woodwind flute
for the French, a French Horn or a Harp (lol)
for the Americans, a trumpet or a fife
for the Italians, a clarinet (like the ones from Giarabub theme song)
Finally, I don't know what the Finnish would play as a national instrument but how about a rack of antlers
