Sorry, you're going to need to explain what you mean by screening here - my knowledge of naval warfare is limited. But surely the role of reconnaissance is going to be enhanced by an increased LoS and range rather than this causing problems?
Screening; basically acting as a barrier between the enemy and the target. Particularly important in anti-submarine warfare, and anti-air unit warfare.
Basically, you want to detect and intercept a threat with your units designed to counter it (eg destroyers counter subs, aegis cruisers counter cruise missiles) before the threat closes in to attack a weak/vulnerable/valuable target (a transport convoy, or a carrier).
This typically means IRL that the vulnerable targets are in the center of a battle group or convoy group, and the screening units are deployed on the edges so as to be able to detect and intercept.
In terms of recon, in an age of sail fast light frigates might be used to search around and locate an enemy fleet, so that you can then bring in your heavy ships of the line to engage them.
Line of Sight doesn't really replicate this very well, particularly vs invisible units like subs. Its boring if my destroyer can just "see" subs multiple tiles away, I'd prefer to have to actually intelligently use it to try to find the sub.
I would imagine the idea is with such a long bombardment range, you need a navy of your own to counter properly.
But how do you counter bombardment? You can't shoot down shells (at least, not with ww2 era technology). Yes, you can have your own navy bombard them.... but then you're just blasting away at each other and able to focus fire, and positioning is irrelevant, so you may as well have had stacks rather than 1Upt.
Same thing; I'm not saying that 1UPT is a typo, it could be. I'm not saying that No Religion is a typo, it could be.
You don't see a difference between a design concept benig explained and a single number?
I would become paranoid and delusional thinking like that.
*Would* become?
More importantly, guys look at post 42.
