Useful to convert British/Commonwealth Bolt Action squads to K47 as squads can now take 2x Brens.

Alternatively if your Bolt Action/K47 Japanese force needs more expendible AT melee punch it is worth considering swapping the bamboo spears of bamboo spear fighters out for something more spicey.

Sword:
Katana. If you want to run K47 Japanese squads smaller with more squad leaders with combat blades, well here you are.

50mm Knee Mortar:
Light mortar, pretty universal for Bolt Action/K47 and can be used as a grenade launcher in warhammer.

Less useful, simply because it is large and metal. Prone to making a resin/plastic miniature fall over. Quite useful for ambulance conversions however.M1 Carbine: Less useful for the Americans in K47, even if it is identical to the fire select M2 carbine, that could be counted as an Assault rifle in the rules. Although it would make sense if these are handed out and/or passed to former/dubious British/Commonwealth allied troops.

RPG7:
Useful for K47 Soviet troops. Also very useful for Imperial Guard Missile launcher teams.

RPG pouches:
IRL these are stacked together, so you will need 2 per grenadier/assistant. So 4 RPG pouches per 1 RPG. And a little bit of work to glue them together and fill in the gaps for the man-pack. Upshot is the little guardsmen get 13 rockets to give to their enemy.

AK47:
Useful for upgrading K47 Soviet Squads to have Assault Rifles.

RPK:
The natural upgrade for avante garde K47 Infantry LMG gunners.
