There can be no doubt that there is a degree of tension between the various branches of the military in all major nations, which is exasperated if there are more than two. In Britain since the end of WWI and the formation of the RAF, their has been a constant low level grumbling by any two of the three about how much money is being spent on the other one. In the USA, the navy and the army were constantly in conflict regarding the allocation of funds, and this ignores the internal fighting that went on within the respective services. In the navy the battleship lobby wanted more money spent on their pet projects, while the aviation lobby wanted more funding for their pet projects, as did the submarine lobby, etc, etc. And the same was true of the army, were infantry, artillery, engineers, signals and armoured all wanted a bigger slice of the pie, and aviation wanted its independence. However no were in the world did the level of hostility between the various branches of the military, degenerate to the extent that it did in Japan. No British general had to worry about a hit team from the navy, taking him out, or an admiral having to be sent to sea to keep him safe from the army hit teams who wanted to rub him out. Because of the peculiar British inheritance system and tradition, first son gets the title and the land, second son gets a commission in the army, third son goes to sea, and fourth son goes into the church. It was common for brothers to be serving in the army and the navy, even on the same station as each other. The most famous was the Cunningham’s one who was an admiral and the other a general, and they did for a time serve during WWII, in the Mediterranean/North Africa campaign at the same time. The intense inter service rivalry that was seen in Japan, wasn’t seen elsewhere, and once the war started, both the British and the Americans, were able to form numerous combined service organisations, and combined international organisations. That is not to say that there wasn’t continued rivalry, and minor spates, but unlike the Japanese, most other nations managed to sort out some form of cooperation between the services. Note that the problems that the Germans had, were more to do with the chaotic system imposed by the Nazis on everything in Germany, than the normal inter service rivalries.
