oh, i made a lot of changes.
i intervened on about 40 units to make them more powerful, making higher the number of javelins, the morale, and so on. gave more arrows and bullets.
i added saddle to some cavalry units, changed the slashing sword in piercing sword sometimes, added the ap (armour piercing) attribute, added also testudo attribute
hide_long_grass to some units (also to few cavalry units), and so on.
didn't change the nature of the units, didn't give them weapons they shouldn't have (didn't give horses to infantrymen, 'f course),

so, i intervened quite a lot on this EDU.txt file...
i intervened on it on the EB/DATA folder, then copied and parted into the SP GAME EDU BACKUP folder.

have to say, i worked quite a lot....

if i loose all this job, i could become quite ... sad
