So basically, the question of Human Wave and Infiltration boils down to whether or not the Night attack bonuses are worth 10 morale.
Well...not quite that simple. Each doctrine path advances at a different speed, with the difference being very pronounced during certain years. Also, Human Wave gets small discounts to mobile units, while Infiltration actually suffers a penalty.
Year.....HumanWave...Infiltration
1936.......40/80............50/40
1937.......50/80............50/40
1938.......50/80............50/70
1939.......50/80............50/70
1940.......50/100...........60/80
1941.......70/100...........60/80
1942.......70/100...........70/130 (+10% night attack)
1943.......70/140...........70/130 (+50% night attack)
1947.......70/170*.........90/150** (+50% night attack)
* - Mechanized and Armor only
** - Divisions with Artillery only
The nightfighting bonus, however, trumps all from 1943 on. +50% night attack means that you are never affected by attacking at night, while the opponent is. Technically, you attack better during the night than they can defend; -30% penalty to their -33%. It's gamebreaking once you get far enough in the game to research it. The final tech makes this gap even wider, even at the cost of a little speed and the cost of the Artillery.
