Randomizing army spawning

[Quinn Inuit]

Is this a good way to randomize a spawn army? I'd like to give it a named character if possible.

monitor_event FactionTurnStart FactionType scythia
    if RandomPercent < 3
    spawn_army
		faction scythia
		character Kudurmabug, general, age 30, , x XXX, y YYY
        unit		sarmatian noble cavalry				exp 0 armour 1 weapon_lvl 1
        unit		sarmatian horse archer				exp 0 armour 0 weapon_lvl 0
        unit		sarmatian horse archer				exp 0 armour 0 weapon_lvl 0
        unit		sarmatian archer			exp 0 armour 0 weapon_lvl 0
        unit		sarmatian archer					exp 0 armour 0 weapon_lvl 0
    end
    end_if
    if RandomPercent > 99   
    spawn_army
		faction scythia
		character Kudurmabug, general, age 30, , x XXX, y YYY
        unit		sarmatian noble cavalry				exp 0 armour 1 weapon_lvl 1

    end_if
