I mainly made these because I need larger things to see and especially reminders what the national bonuses are for objectives. We always have a new player joining and he does not quite remember what is required to get the bonus.
On the battle board I added information about surprise attacks and anti aircraft as people forget to roll these first, Kamikaze information, and how to do strategic bombing runs.
Say the Japs had DEI & Phil, and its main force is at Carol Is. Ideally if you could get 5 allied subs in range you could spread them out in 5 different sz all at once costing Jap $ (8-10 ipc) and forcing them to buy more DD’s to go after you. At the very least it could be a stall tactic or weaken the Jap force. Jap would need to make a choice to attack your main force w/o DD’s (cheap causalities), or leave the convoy raids in place. If Jap goes after the subs, you may have created targets of opportunity to go after.
On a side note, I wish tactical bombers were able to bomb air/naval bases (not factories). According to my grandpa’s carrier’s war journal, they did a lot of airfield attacks, so it would only make sense to have that ability, and it would better justify the 11 IPC cost, since some people think that is too much.
