Naval editor questions

[Nginear]

Two questions:
1) I noticed defensive fire happens when an amph-transport and LRT stop next to an enemy ship, but it does not happen when a regular transport is next to an enemy ship. Is it possible to control defensive fire - increase, decrease, or what ships it happens too?

2) I added a naval attack amount onto a LRT with a strike distance, but it still will not attack another naval ship. Am I missing anything?

Thx

These are both engine based features and are not editable I'm afraid, e.g. the defensive fire is just designed to impede amphibious invasions, and amphibious transports can only attack land based units.
