Well I would like to make a change to the periods. Placing generals ahead of Napoleon himself in the Napoleonic bracket is just wrong. Napoleon set the standard for Napoleonic warfare. Marlbourough for instance should most certanly not be there and since you have included him you would have to include Charles XII.

Id rather see you took away "renaissance bracket" and replaced it with "Early modern bracket", approximatly from the end of the middleages until Napoleon.

Since im Swedish ill give you some must have Swedes in that bracket;

Gustatvus II of course (u allready have him)
Charles X
Charles XI (possibly but more of organiser then fieldcommander)
Charles XII
Johan Banér
Lennart Torstensson
Carl Gustaf Rehnshiöld

There are a few more but all of the above would be very competitive. There are also missing some from other countries but (Turenne for instance). ill let it rest here.
