He means that when you transport tanks you have three to four"hits" in a single transport.
IE: two transports landing 3 tanks and an obligatory infantry can take 7 hits before being wiped out(3 of which are ignored)
With infantry only there are no free hits, and 4 hits wipe them out.
Bottom line: Tanks are economical to transport if an amphibious assault is in the plans.
On the note of soaking up hits. Since a tank is less effective than an infantry in combat, and costs twice as much, it must soak up two hits and still survive before it has “earned it’s cost”. This means at least two attacking rounds. If tanks are bought turn 4, and see combat turn 6(assuming it takes a minimum of two turns to get somewhere useful), it would take till turn 8 before a single tank on the board could have earned it’s cost. I feel the game’s fate may already be decided at that point.
In the end it may only be a good investment for the States and Britian due to the transport advantage, and britain can likely transport them off the factory to a frontline spot in a turn.
My current predicition is that if there is a 2nd edition tanks will either decrease in cost an IPC or gain +1 to attack and/or defense.
