Which supports your conclusion how?
Having two separate formations isn't particularly useful. Calling it out as a waste of tonnage seems odd, it's more that it just doesn't help at all
That's it, above all: I think
consiefe was not opposing this obvious trash, so "formation" have to be a typo, it have to be "element" there - just as we discussed above that post (my starting replica was about elements too: "IIRC, there is no non-RP reason to duplicate HQ elements to lower chance of beheading strike"), and then
consiefe answered writing "unit" instead of "element", and therefore no disbeleave in further typo - "formation" instead of "unit".
And if it was about 20x full-size HQ elements... well, that's obviously not an improvement:
Infantry HQ is 1% of their command limit size (10t for 1000t command limit).
So, 20x full-size HQ is 20% of overall combat force.
With the same principle in all command tiers you'll have 51.2% of tonnage to HQ elements only for 3-tier infantry-only force (regimental - that is plausible force to knock out fortified standart battalion-level mining colony garrison of the same tech level without heavy loot-cracking orbital fire support - thats what infantry drops are for, yep).
MV HQ is 4% to 8.8% of their command limit size, depending on secondary equipment.
So, 20x full-size MV HQ is 80 to 178% of overall combat force.
For army-level with MV HQs... you'll leave no tonnage for combat and logistical elements at all.
It's obviously
not what
consiefe talked about.
Having multiple HQ units within your HQ formations (and probably also every front-line formation) to provide some resilience if the HQ element draws fire is very useful.
EDIT: And in particular, it reduces the risk of your commanders dying and leaving you with your problem of not having on-site replacement officers, as well as reducing the risk of a formation losing all HQ units and breaking the chain that way.
Well...
I'll be recurrent.
1.
Adding full-size HQ spare element to your HQ formation (that is - doubling HQ formation size) is doubling the chance this HQ formation will be chosen as target. So, half the chance of KIA, but double chance of hit to get that half the chance. So no advantage at all.
2.
All this HQ size will be substructing from your drop force combat (+support and logistical) elements.
For infantry-only force it will be -1% per 1-level spare HQ, that's smth like statistical error.
For MV it will be -4 to -8.8%, and it's quite noticeable loss of combat elements, but if you have commander with several 20-30% of relevant bonuses - that's good for 1-level force, if it's effective measure to save this commander and their bonuses. Multi-level forces will be more questinable even if no "1." point.
