The Duck is an amphibious bot equipped with:

1. Short-range medium laser
2. Light torpedo launcher

Useful for raiding unprotected naval structures and sneaking into enemy territory from the sea.

It's also a good way to allocate a quick moving amphibious torpedo unit to aid your naval units.

In masses they can turn the tides of a naval battle and break through to the enemy economy. Be careful relying solely on its weak laser beam is not advised.
