First i ask what game you play ? The Legend , Armored princess/Crossworlds or Warriors of the north. Because for the Legend last patch was 2 years ago, and nothing was changed since then, same goes for Ap/Cw. But original Swordman/Guardman speed is 3, only difference is Swordman have initiative 3, and Guardman 4.

Check their in game settings in game folder/dat/data.kfs and find in there footman.atom for swordman stats, or footman.atom for guardman. Open that file with notepad/wordpad and browse unit in game statistics. But this is stats they have in all 3 games :

main {
  class=chesspiece
  model=footman.bma
  cullcat=0
}
arena_params {
  features_label=cpi_footman_feat
  features_hints=armor_header/armor_hint,alertness_header/alertness_hint
  race=human
  cost=70
  level=2
  leadership=35
  attack=10
  defense=16
  defenseup=4
  initiative=3
  speed=3
  hitpoint=35
  krit=8
  movetype=0
  hitback=1
  hitbackprotect=0
  attacks=moveattack,moveattack2
  features=armor,humanoid,care
  resistances {
    physical=20
    poison=0
    magic=0
    fire=0
    . . .
  }

As for smashing blow, it`s neat ability for almost 50% more dmg then normal attack for that unit. But later in game if you have high enough crit% almost every attack from unit will make 150% dmg and smashing blow become useless.
Have fun
