Dumb question about S-300 Switchblade

[Mgellis]

All right, it looks like the S-300 Switchblade and the S-600 Switchblade are both in the database (4133 and 4134 in the Weapons category), but I cannot figure out what units have them. Is it a facility? A ground unit? I tried adding it to a platoon of marines as an extra weapon, but that didn't work, either. What am I doing wrong?

Thanks.

I think the weapons are there but no default platforms or a weapon record to add to another unit.
