Rambo Squad Alert !

[ShadowAUT]

Hmm in the Austria OOB, the Jagdkommando (which are the austrian Special forces) have 2 types of Units:
One equipped with:
STG 77
Hand Grenade
MG74
Satchel charge

The second type has:
STG 77
Hand Grenade
MG74
Panzerfaust3

I think its okay, I take the satchel JagdKommando if I want to do real commando missions with them, so blowing up bunkers or enemy Rara AA Guns etc behind enemy lines.
But if I have no intentions in such commando missions, it makes sense to take the second alternative, the Panzerfaust 3 instead of satchels.
Then the JagdKommando is a support Unit for standart infantry missions as every jaegergruppe does.

I think you should change the KSK same way, if you intend to use the KSK squad for fighting like standart infantry, give them Panzerfaust 3 instead of MILAN.
If you want to use them as defense unit against armoured targets, use a MILAN equipped KSK Squad (which then should have not an MG3. Instead of this, there should be another KSK Squad covering the Milan Squad.

The third KSK Squad Type should then be a demolitions squad.

Maybe a fourth option with a heavy sniper for scouting duties behind enemy lines would be somewhat realistic too, but this sorts of operations are usually the work for Fernspäher.

In reality the standart KSK Squad is:
1x Medic
1x Demolitions Expert
1x Radio Expert
1x Weapons Expert

The standart weapon loadout usually contains "light" weapons. the Milan is not a standart weapon, it will never be, because a MILAN needs at least 2 (if not 3) operatives to carry the weapons+equipment+ammo.

I give you a hint: change them to somewhat realistic squads, I did the same for the Austrian OOBs, where I have found so many errors meanwhile, that I had to undertake massive changes to austrian OOB.
