These look more like batteries than cartridges.

The steel ones in black are blank inserts for Czeh RG-4 practice grenades. The short ones (actually tinned steel I think) are “PP-9” “pyro-cartridges” (actuators/igniters).

Thank you. The igniters are ALUMINUM. What are they used for ? Does the color mean anything? All 4 are different.

I think the color itself has no meaning since the boxes do not inidcate any charge strength or so. They are just distinguised by size and designation.

What are they used for ?

I just saw another view of the ones I thought could be batteries…they definitely are cartridges.

Practice version of the RG4 impact grenade.
After resetting the impact mechanism the safetypinwas sealed.
It held a smoke charge which could be replaced after use.
