Further to planetary invasions the current logistics rules do not work without horrendous micro management. Need to set it up that combat units can draw from a supply dump in the rear area.
This is already 100% possible. The trick is you must use LVH+LOG units for this to happen (representing supply trucks). INF+LOG will only resupply its own formation, the LVH type is capable of resupplying formations which are subordinate in the hierarchy. Of course, also note that the formation hierarchy must be followed as LVH+LOG can only supply subordinate formations to their own formation.
I also think logistics requirements need to be considerably reduced.
Disagree. If anything, logistics requirements in Aurora are rather low compared to those for a real army at least in terms of raw tonnage of materiel transported.
The second point is on the initial landing it appears that defending units are attacking while still having the benefits of Forward Defence. This means that the initial landing forces are devastated without the same ability to counter attack the defending forces. The defending forces should loose the benefit of being dug-in while attacking. (Yes I am assuming that is what is happening. I was higher tech and loosing 200-300 vehicles every eight hours while the defenders only lost 100-150. All my units set to Forward Defence but with only 8 hours it was insufficient to dig-in.) Perhaps I misunderstand what is meant by Forward Attack and Forward Defence?
As other commenters have alluded, both front line attack and defense positions are able to fire at the enemy without hindrance. The main difference is the use of evasion and fortification, respectively, to reduce the enemy %chance to hit. The attack position also gains the ability to conduct breakthroughs and capture the enemy colony once the ground force has been defeated.
Finally eight hour combat rounds are far too frequent and a hit rate of 1.5% is far too low. I also think ground force production is still too low. In the current invasion I only had 1 million tons of forces (almost my total production in game so far) to invade with but the defenders had a visible 450,000 tons of defenders.
Not agreed on hit rates as the pace of ground combat seems reasonable to me, however GU production is problematic as planetary invasions are quite prohibitive against alien homeworlds. This may be a case where realism and fun gameplay are divergent and should be looked at. As it stands any homeworld invasion all but forces a long bombardment period which destroys the actual colony in the process, so that conquest becomes largely pointless.
