I don’t know if ever one wrote about this, but this may be of interest:
Whenever you play Axis & Allies, you have to define in the first round your VIUs and the one of your opponents. VIU are very important units.
Typical for VIUs is:
- you have them from the beginning
- you cannot afford to lose them
The last point has to different forms:
VIUs that can hardly be replaced because of their costs (e.g. battleships) and/or VIUs that you can’t replace, because it takes to long to reach that place (e.g. the 2 UK infantry in South Africa)
Once you defined VIUs on the board, the VIU theory says:
- Never lose your VIUs sensless
- Don’t attack with VIUs unless it’s overwhelming
- Kill enemies VIUs whenever possible
- try to build additional units that may replace your current VIUs
- help your allies to protect their VIUs
- trading VIUs with the enemy can be good if the future consequences are checked
- don’t rely on lucky dice when attacking with VIUs (e.g. never SBR if your bomber is that precious)
–----------------
Examples:
UKs Battleship in SZ2 and UKs Tank and Fighter in Egypt are VIUs (expensive + hard to replace). Attacking them as Germany is highly desirable. For UK killing the German cruiser + transport via air attack is desirable too, as well as for UK and US is a goal to kill the Italian fleet.
VIUs in AA50:
Russia:
Only the sub in SZ 4, because you will hardly ever have enough money and less pressure to build navel units again, don’t lose your tanks or newly build air units
Germany:
the bomber, your fleet, the African units
Japan:
only the battleship, all other units are near Japan and can be replaced
UK:
the BB, the bomber, 2 Inf in SA, all units (ground + navel) near Australia, all units from Egypt to Burma
UK has naturally the most VIUs due to the vast distances to reach them. Units in SA, Egypt, India and Australia will lose their VIU status if an IC is build there, as they can now be easily replaced
Italy:
fleet + fighter (Italy is lacking funds)
China:
the fighter
US:
as the 2 Inf and fleet at Philippines can’t be protected, US has no real VIUs, anything can be replaced. Yet its fleet at SZ 44 should be kept, those units are valuable
