Where can I find the site to check what I will be issued prior to my deployment to Poland?

SPC (Join to see), I've never seen a web page that tells you what specific equipment will be issued for a deployment. Your "my property" page on AKO has your current assigned equipment, but doesn't project future equipment based on deployment. Usually there is a list published from the CIF at your installation. Even then, I was usually surprised by the equipment issued prior to deployment.

Goodluck on this, RFI issue depends on the Unit Mission and funding.

RFI is issued by operation you’re on. OEF, OEF, OFS, etc...Your CIF should be able to answer the question.
