Broken sACU Presets

While renaming the Nomads sACU, I've noticed that it contains some presets that are broken (and possibly out of scope).

The presets that are broken are:

- Amphibious
- Anti-Naval
- Rocket Launcher
- Heavy Trooper
- Rambo

This may be related to local changes, but please let me know if this is reproducible.

Start by reproducing the Amphibious, Anti-Naval, Rocket Launcher, Heavy Trooper, and Rambo presets in the Nomads faction. Check whether each failure occurs without local changes, then trace the corresponding preset definitions and unit data. Done means the broken presets work as intended or their out-of-scope status is documented.
