The faq mentions :

A suggested attacking army for a Catholic faction would be
4 men at arms (use the most recent available to you),
4 spears (use sergeants of the most recent type),
3 ranged troops (archers, crossbows or arbalesters depending on the era),
2 heavy cavalry (knights of the most recent type),
1 light cavalry (the faster the better, these guys will be used to run down routing enemy troops)
2 anti armour troops (militia units until 1205, after then use a unit with pole arms like halberdiers).

Ok it says, use cavalry if you are non-catholic.

I start with the early period
for heavy cavaly ---- > armenian heavy cavalry
for light cavalry ---> ottoman sipahi
ranged troop ---- > ottoman infantry
spears ----- > saracen infantry

well i am confused for men at arms part. turks dont have those units, what should i use instead ?
