Received request for military service details from CIC

[Lord_Tony]

Guys, maybe somebody can help me to fill out the IMM5546 form. My partner is serving in army right now, but we cannot disclose all the data, that they requested, what to do?
There is a war in my country, and some information is classified as secret

Mate considering your situation and risks better approach an RCIC, professionals who can give the right advice than folks in this forum. Not many folks here would have faced your situation
