My try:
0/0 - settler, worker, leader, scout, explorer, catapult, cannon, artillery, radar artillery, cruise missile, nuclear missile, ICBM, stealth fighter, stealth bomber, army
0/2 - bomber, helicopter
1/1 - warrior, jaguar warrior, chariot, galley
1/2 - spear, impi, caravel, galleon
1/3 - hoplite, pikeman
2/1 - archer, war chariot, horseman, privateer*
2/2 - bowman, frigate
3/2 - swordman, man-o-war
4/2 - immortal, fighter
4/3 - knight, war elephant, rider
4/4 - samurai, ironclad
6/4 - cossack, submarine, nuclear submarine
8/4 - jet fighter, F-15
16/8 - tank, panzer
* - privateer might go in the 1/1 line...I remember they were REALLY lame in vanilla.
That's all I got (seems the 3/2, 4/2 (or incorrect), 4/4, 6/4, and 8/4 were missing from earlier lists...).
