By "Pacific" war, I am specifically excluding the use of tanks by the Russians (or Japanese) in Manchuria, in 1945, or earlier "border clashes" along the Mongolian border in the late 1930s.
My understanding is that on most Pacific islands, tanks were useful for overcoming strongpoints, demolishing bunkers, etc. but not for the breakthrough and encirclement movements that characterized the European "blitzkrieg." Therefore, tanks tended to be deployed in multiples of ten at a time, not hundreds at a time. Put another way, tanks were used in "French" style, that is on a small scale for infantry support, rather than in "German" style for large scale encirclement movements.
I didn't see evidence of large scale tank deployments by the Allies even in relatively large areas, such as the Philippines or Burma (Myanmar), probably because of the weather, rough terrain and generally bad topography.
So was the above, in fact, generally true in the "south Pacific?
And was the (occasional) Japanese use of tanks also limited to infantry support (outside of China, Manchuria, Mongolia) or were there instances of Japanese large scale encirclement movements in the tropical regions?
