Italian Campaign
Difficulty - Generalissimus
As per usual these days.
Traits - Aggressive Deployment, Arrogant, Master of Blitzkrieg
An immediate surprise is that I cannot select any of the supply related general traits, they are disabled for the Italian campaign. I wanted to try out Chaotic Fire, as it seemed flavorful given the issues Italians had with their mid-level commanding officers, but sadly I need to explore other options I have not tried out before. Poor Ground Control seems like an especially horrible idea on desert maps, so I skipped that. Slow Reaction is something to test out on more hero intense runs, with plenty of support fire, but I can't deny it would fit somewhat... Given the options remaining, I went with trying out the Arrogant trait. It will be interesting to see how much my own memory of the rules and stats will work out. I guess Bernardo is really looking up to his older brother and thinks he can succeed as much! For positive traits, I'm going with Aggressive Deployment and Master of Blitzkrieg, for a fast motorized core, an elite of the Italian army that ties in to the Arrogant trait in a way. Crossing of minor rivers will probably not come up much, but that +1 movement for tanks can help for sure.
While I am not using the Collector extra rule, I'll try to not duplicate units where possible, maybe aside from infantry.
Hero:

If I understand correctly as with the Bulge DLC two heroes are random and one is pre-set. Considering this, Gabriele Demarco is a great roll, allowing me to ambush British tanks in the desert. Other uses of Camouflage come to mind, but I prefer to be able to counter Matildas reasonably.

Another great hero, Tommaso Greco will be a fighter pilot for sure! Even the photo matches this idea.

Finally the last hero, this time one created by the designers directly. A clear infantry choice (and even a historical infantry commander). I am just pondering if it is better to use him more for engineers due to the first trait, or cavalry due to the latter.
Frontlines: Cyrenaica - Invading Egypt
Starting Prestige: 335
New Units Commissioned:
3º Battaglione Carri - L6/40
1º Battaglione Cannoni Controcarro - OS12 - 47/32 M35 (Truck)
2º Reggimento Artiglieria - 100mm 100/17 (Lancia 3Ro)
1º Compagnia Mortai - Mortaio da 81 M35 ATY (Truck)
1º Gruppo Caccia Sq 2 - MC.200 Saetta
1º Gruppo Caccia Sq 3 - OS11 - CR.32
1º Gruppo Bombardamento Veloce Sq 1 - OS11 - Breda Ba.65
Yes, I know that the L6/40 was not used in Africa at this stage, but I'll take what I can get! Other then that, a towed AT gun is a cost efficient unit to get with Camouflage. Some extra artillery will be critical for Italians and I am very curious about mortar infantry. Extra planes also can help given long distances to cover and the CR.32 is a compromise nod to history, a bit of a way to even out justifying the L6/40 unit.
New Equipment Provided:
1º Reggimento Bersaglieri - Bersaglieri (Truck)
1º Battaglione Carri - OS11 - L3/35 Lf
1º Battaglione Autoblindo - AB 40
I get better infantry, some flame tanks and a recon car instead of the motorcycle. The last change is purely for unit naming reasons, since I was not able to research a believable name for a motorcycle recon unit, as they were apparently used in support role for infantry formations and not really as standalone formations.

Highlights

I guess the briefing canonically confirms the Arrogant general trait?

First lost unit found in the desert. It joins as an auxiliary tank, which is appreciated. Too bad I am for now stuck with less stellar vehicles in the core force.

Arrogant trait does not show combat predictions when moving next to the enemy, so far so good, as expected.

Also works fine on attacking, that's good as well.

Interestingly, defensive predictions still remain. That's probably not as designed. It can probably help a bit in certain circumstances, but I'd prefer it also would show nothing. Since attack is rather different than defense and not equivalent in predictions, it is not very abusable, but I'll refrain from looking at this if I can help it.

Ferocious fighting for the outpost on the way south.

That airport near Musaid will be critical, my planes are struggling with range.

I decide to take the main road as time is of the essence and I've dillydallied for a bit to long. I still send some units around the desert to see if they can help encircle British positions.

My fighter planes do not have anything useful in range, so they switch to a scouting role and ultimately find remaining two missing tank units. That hero is a very useful one to have, as Provocator is a powerful way to break through defensive positions or deal with dangerous counterattacks.

All that is left is to capture Sollum. Looks like I was unnecessarily concerned, as most of the heavy fighting happened early on in the scenario. All that was left later was to mop up a few remaining British units.
Summary
Final Prestige: 2801 (up 2466)
Overall
First scenario and a very positive prestige trend is a welcome sight, as it gives me time to build a reserve in case the difficulty spikes later on. I liked the mission, as it was a constructive demo of what I expect to find on the desert further. It taught how to handle terrain well (dunes are surprisingly tricky to navigate and deceitfully safe), it showcased how powerful aircraft are, but how limiting the range on planes is and how absolutely critical airfields will be, as well as allowed to check how individual Italian units behave depending on core composition. I Immediately liked the mortar infantry, especially with the Aggressive Deployment trait, as well as the 65/17 M13, but it will need some experience and heroes to get some extra firepower. I was less impressed with Ascari del Cielo due to not giving them truck transports. Since I am unlikely to get options to use them as paratroopers (as per the historical limitation), I need to think of them as normal infantry, but cannot justify using them non-motorized, the maps are just too big for that. Their Camouflage trait so far did not pay of, but can be potentially very powerful if I increase their mobility.
As for the traits I selected, Aggressive Deployment is working well. I just realized I selected them same for "War Stories: Fall of Poland", so I promise, for the British side I've got something different in mind. Extra movement on tanks also was quite useful, not to cover more ground attacking, but rather to return within support fire range. Arrogant is certainly unusual and feels it will take time getting used to. I did not stumble due to it at any point, but then again, I was in a position when the enemy was often attacking me instead, so the issue rarely came up. I guess it will be all about closely monitoring suppression levels and entrenchment, but so far aside from taking some more losses and slightly increased prestige spend it should not be a backbreaking limitation. Of course I reserve the right to be wrong and make some silly decisions in the future. I also noticed that an AT gun with Camouflage is more difficult to abuse than normal. Since the British have many recon cars, I need to prioritize their destruction, else a well laid trap might backfire entirely.
