In Axis and Allies, Should the U.S. Build a "Factory" in Brazil?
I can't imagine an instance where a US factory in Brazil makes much sense. Let's look at the supposed advantages one by one:

It can produce THREE units per turn - Yes, but the troops are not in a strategic position. The only territories to which you could move the units and not move your transports out the way is to: French West Africa; French Equatorial Africa; and Belgian Congo.

It is directed against the GERMANs (in Africa) - Yes, but unless Germany has some lucky dice rolls, you should have them hemmed into mainland Europe by turn 3 to 5. If you let Germany hold Africa for any significant amount of time, the Allies are fighting an uphill battle.

It won't be captured unless the U.S. player is extremely careless, not merely &quot;unlucky.&quot; - True, that is a benefit over a factory in Sinkiang, whose sole purpose it seems is to help hold back Japan's march into Asia.

An American transport in African waters can go offshore Brazil, pick up two infantry, back to Africa and unload the infantry all in one turn. - True again: it only requires one turn to shuck troops from Brazil to Africa. However, it's also only one turn to shuck troops from Eastern Canada to Algeria (see the &quot;shuck-shuck&quot; from Don Rae's excellent essays on Allied strategy). The East Canada transport basing has the benefit of being able to attack Africa on turn 2 or 3 (just like best-case Brazil), but it also leaves the transports in position to support Finland or Western Europe instead. This is especially important because it allows the Allies to obfuscate their intended point of attack and/or change it on a whim based on Axis play. Once the shuck is set up troops hit the Europe or Africa every turn.


It seems to me that the sole advantage of a factory in Brazil is to take Africa from Germany. But it's a slow and costly way to do it.
My Approach to Claiming Ally Control of Africa
Here's my strategy to quickly secure Africa from Germany's grip:

On turn 1, the UK needs to sink as many German naval units as possible. If you're lucky, you'll have a sub, transport and/or battleship left that you can use to attack/as fodder, but even minus that you likely can use your Indian or UK fighters and UK bomber. The idea is to eliminate the German navy ASAP. This needs to be one of the Allies powers' early game goals.

Cede India and go into Africa hard. Depending on the Med. naval situation and how many troops are on the ground in Africa, as UK I'll typically reinforce (or retake) Egypt using my troop in Iraq and two in India.

Once the UK/USA navy has secured the Atlantic and are sitting in the UK sea zone, have UK move its transports into the Spain Sea zone and drop off at least four infantry. The US needs to follow suit on its turn to protect those transports from the German air force, dropping more troops into Algeria.


Everything hinges on eliminating that German navy sooner rather than later. If you let the German Med. navy sit around past the early game it can be difficult to combat Germany's growing industrial capabilities thanks to the extra 11 IPC they're getting per turn by holding Africa.
But What If the Allies Don't Take Africa Early?
But what if the Allies don't take Africa in the early game? What if the UK pulls her African corp to India? What then?
I still hold that a Brazilian factory is out of the way and not as logistically efficient as transports in the Spain Sea zone. For starters, you need to commit and move transports into the South Atlantic. This takes those transports out of the North Atlantic, where they can help protect the UK and USA navies that should be focusing on dumping wave after wave of infantry into Finland en route to Karelia.
US transports are ideally situated in the North Atlantic because it allows them the greatest range of options. From the UK sea zone the US can drop troops into:

Finland
Western Europe
UK

They can move to Spain Sea zone and still in one turn send troops to:

Western Europe
Spain
Algeria

The North Atlantic allows the most range of motion and allows the Allies to project their will into Europe and Africa. From Brazil, the Allies are limited to just Africa, albeit a with a wider choice of landing zones. But I argue it's best to keep the US/UK navies together in the Northern Atlantic so that they can project their will together and so that they present a less appealing target for the German air force.
