TL,DR: Swiss law is different than U.S. law, and it's hard to generalize as each is more or less permissive given different areas (and the U.S. is really 51 or 52 little countries in most senses, as Switzerland is divided into Cantons).
TL,DR: One can buy ammo freely at ranges and with minimal permitting to take home. It sounds like maybe the Army wanted ammo stored centrally such that it would be in controlled environmental conditions, and not lost or accidentally used up at a Schützenfest.
