Hello,
the two medals with the chain are:
the silver medal memory of XII Regiment Infantry CASALE
present of the battalion ranks and engraved with
the name of the seargent CASALE AURELIO (for the good service I think)

The medal S. Martino di Castrozza m. (meter 1444) is an mountain war
location of the WW1 the medal is not military I belive is an war memory.

The medal of ship Regio Esploratore BARI in silver.
