Bolt Action Zombie - German zombie types

I am thinking of three types of zombies for my WW2 game.

  The nastiest will be SS Zombies - these are creations of an occult experiment conducted by high ranking members of the SS.  They will be fast, hard to kill, able to climb, use things, be semi intelligent or better, have leadership and, fortunately, be in limited numbers.

The nature of their creation is what makes them dangerous and hard to kill.
 
 They wont have the ability to infect others. They are pure killing machines and nothing else.

Type one zombies

 Next will be your German soldier that has become a zombie through chemical testing to create a Super Soldier. They will be harder to kill, but lack the ability to move fast, climb or use items. Basically a normal zombie, only harder to kill than average.

 Only 'first generation' zombies will be harder to kill; basically only those created through chemical testing will be tougher.

 As they were created in a laboratory  through experiments that have gone wrong, they will carry a virus that infects others that they bite.

Type two zombies

 The third, and last type, of zombie are those bitten by the 'type two' zombie.  They can be other German soldiers, Allied soldiers or even Civilians. They will be easier to kill but still remain infectious, thus passing on their undead curse to others.

Type three zombie

 What does all this mean in game terms?

Type One: can run, open doors, climb ladders, has a troop quality of 10 and is killed on a 6+

Type Two: slow moving, has a troop quality of 9 and is killed on a 5+

Type Three: slow moving, has a troop quality of 8 and is killed on a 4+

The levels as to which the different zombie types will spawn also matches how hard they are to kill. Thus a Type One will only spawn on a 6+, whilst a Type Three will spawn on a 4+.

I will have to play test the different zombie types, but I think they will work.

How to tell the difference between these zombies?

 The Type One zombies are easy to tell - they wear the SS uniform.

For the Type Two zombies I am thinking of painting yellow "glowing" eyes. They will also be in Wehrmacht uniforms.  The reason for the glowing eyes is to tell them apart from Type Three zombies in uniform.

 And Type three will be anything else.
