End of the Japanese Amphibious bonus is here....
At the risk of sounding uninformed, I can say that I'm not sure when the Japanese Amphibious bonus really ends. I thought it was 31 Mar 42. But in my current game, I performed a landing in early April 42 and did not incur the high disruption that I expected for being completely unprepped for the target. Unloading was very fast using merchant shipping. I changed my theory, and thought that maybe the bonus lasted until 7 Apr 42, as the manual says that it lasts "4 months". However, later in April, I did a divisional landing at Ambon with troops completely unprepped, and did not incur the drastic penalties expected. Now my theory is that it ends at 30 Apr 42. I haven't done a landing in early May yet to see the penalties.
I realize that I should know by now when it really ends. I thought I did. I'm judging my theory on my observations, which doesn't prove anything, but certainly changed my mind. My Ambon division should have been wrecked on landing, in my opinion, if the bonus had expired.
This is a long discussed topic, and one that I thought was settled, but it is not for me at the moment.
High experience in the LCU also seems to minimize losses during unopposed landings. Just my observations, I haven't tested the theory.
