An invasion or raid on Darwin would have had to be accomplished quickly. As a result, much would have been demanded of the assaulting forces and delays of any kind could not be tolerated as it would leave the attackers at the end of a precarious logistical tightrope and force the IJN to defend a set location, something which, time and again, resulted in unsustainable losses to their fighting ability.

So the idea of entering with an admittedly superior force of infantry and having to essentially clear out the entire board in order to have a win in this scenario seems fair. Unfortunately it also seems virtually impossible. There are too many objectives (a hill and two towns and two boards of roads) and the rare situation where the Aussies can put up even an hour long fight for a location will hamper the Japanese timeline too much to permit a win.

It became apparent by the three quarter mark that the Japanese could not pull off the win despite ultimately winning every engagement they were able to initiate. There simply wasn't time as the hill had taken an extra hour to subdue right off the bat. They then moved to fight for the draw by denying the Austrailians a place on the road. There simply were too many surviving troops, however and by that time the Japanese had been whittled down enough to make it impossible to cover the road completely.

Tactically I found the Japanese HMGs to be useful only in DF attacks. By using them in assaults you lose the Japanese infantry assault bonus which is worth a lot more than the extra 2 factors of DF they provide, and the Japanese force is amply supplied with leaders. A Japanese infantry assault of three INF will therefore go in on the "24" column at least, and if the leader has a combat bonus they will go in on the "30" column, barring any defensive shifts (they get morale, leader and Japanese infantry assault bonuses).

In the final analysis both forces lost 18 steps but the Austrailian force remained coherent which simply was too much for the Japanese to acheive a victory or pull a draw. This is a tough test for the Japanes and one which will force a very aggresive approach to pull a win or draw. The Austrailian air force made itself felt with three steps to their credit, even the Wirraway (DF factor 6) bagging a demoralized gun. Despite the situation and fun forces I can only see this one carrying a "3".
