79. Canada - Fascist
Fascist Canada that take over most North America (and maybe South America if lucky)
In order to fulfill Canada's manifest destiny to rule America, the reigning king had to be deposed and toppled. Of course, in a literal sense the King of the United Kingdom was rejected due to dynastic scandal, which served as a good excuse to begin true independence from British dominion. But the real enemy would be the United States. The sleeping giant.
The United states had an industrial base and population one hundred times larger than Canada's, yet Canada must find a way to triumph on the field of battle. The answer would come from the royal mounties. No longer royal, since the new independent republic was established, the cavalry unites were used to train the new army, and as a result most of the army was able to converted to mobile infantry, thanks to the mass acquisition of horses.
These horse-mounted infantry divisions were very small. With great conscription effort Canada was able to mobilize enough manpower to have an army just barely as large as the US peacetime volunteer army. However, the American divisions were concentrated in their deployment, with large amounts of firepower, but low mobility. The small Canadian divisions had no heavy weapons and could not survive a few hours in direct combat, so this was not how Canada would fight. The lack of guns and surplus of horses gave the small Canadian divisions a huge mobility advantage. The size of the divisions meant many more divisions were fielded, conferring a strategic flexibility advantage. Once all available manpower was in the field, war was declared.
And there weren't enough US divisions to cover the entire border, so Canadian units selectively advanced and broke through gaps in the line. Every time contact was made with the enemy, advance would stop and redirect towards the side, completely flowing around opposition like a river around a boulder. Using this strategy, advanced elements penetrated deep into American territory without resistance. The war still took over a year due to the sheer size of the country and the unwillingness of the government to surrender, even though the population was not interested in resisting.
Thanks to this experience in speed, emphasis was placed on the development of armoured vehicles. at first, light tanks were employed, but planners realized that their increased speed was of no use in the jungles of the South America, and that the armour and firepower of medium tanks would better protect the precious manpower of Canada. Also, motorized vehicles replaced horses, allowing divisions to keep up with the tanks.
Thus, the invasion of South America, starting in Mexico and flowing down through to Panama very quickly. Some individual points of resistance delayed the advance. But pure infantry digging trenches in jungle could only hold as long as they had men to spend in the meatgrinder beneath the Canadian tanks' treads.
The real bloodbath started in the invasion of Colombia. The amphibious assualt units to take the Carribean were not yet ready, so the tanks to advance from the chokepoint of the isthmus of Panama. Colombian soldiers bravely charged at the tanks to prevent them from advancing, but only at huge cost of life, while the Canadians suffered few losses due to being shielding behind their powerful war machines. Eventually, after over 200,000 combat losses, the Colombian army structure broke, and the Canadian army pacified the country, from there launching to invasions of the rest of South America.
As for the caribbean, it was a simple matter to steal the various island colonies, because they were all occupied by Britain, which was distracted by a major war against Europe. They were not doing so well, but were doing fine in Africa, where they made strange allies with the communist french-in-exile...
