At the moment Axis Tunisia is the only faction (together with Axis Stalingrad) that has not received any vehicles or event units or even drop twitch excluding gold soldiers and event weapons redeemable in multiple campaigns (just to say the allies in Tunisia have 2 event squads and two twitch vehicles).
With the future separation of Tunisia factions this suggestion will be mainly focussed on italy but there will be something for the germans as well ( DAK ).
EVENT SQUADS
P.A.I. (Colonial troops)
The Italian African Police (previously Colonial Police Corps), acronym P.A.I., was a police force of the Kingdom of Italy operating in the Italian colonies of Africa from 1936 to the end of the Second World War.
The game version consists mainly of 4 PAI colonial troops and a PAI officer armed with the first production version of the MAB 38 and this squad can also be a nice addition for owners of the AB 41 with the PAI skin
Team composition 4 assaulter and an engineer

Armament
MAB 38A P.A.I
This initial version has some differences from the more common version such as a folding bayonet, different recoil compensator and walnut wood
Billao dagger (for all squads with colonial units)
The billao, or billaawe, is the legendary dagger that the dubats wore on their belts, on the right. Also used by the askaris and zaptiè of the Italian Regio Esercito is the characteristic Somali dagger, handcrafted, with a large flat and asymmetrical blade with a handle in horn, bone or ivory, and a finely worked leather sheath, replacing the bayonet of the rifle.
"Fanti dell’aria"
( With the recent addition of paratroopers and a dedicated event i think its a good time to suggest this unit. )
The “Fanti dell’aria” parachute regiment, all of Libyan nationality, was the first military unit of paratroopers of the Regio Esercito, born as a battalion on the initiative of the Air Marshal and governor of Libya Italo Balbo at the military airport of Castel Benito in 1938.
Team composition 5 paratroopers
(colonial troops are very common in all units of the Italian army and could be a good source of event units for enlisted )
EVENT VEHICLES
5 cm PaK 38 L-60 auf Fahrgestell Sd.Kfz. 231 ( for germany )
Sd.Kfz. 231 modified with a 50mm Pak 38 cannon
Has good mobility and a good gun but has limited traverse and is poorly protected on the sides of the gun and needs to be used at long range, can use its height to hide behind cover such as hills exposing only the gun.

Fiat-Terni (Tripoli) on SPA38R
Armored car with good mobility and a Breda-SAFAT 12.7 heavy machine gun
in addition to being very effective for eliminating infantry and attacking lightly armored vehicles it can also be used as a light anti-aircraft due to its excellent gun elevation
On the other hand its wheels are quite exposed and easily damaged and its turret even if it offers you good cover from small arms your crew can be killed by thrown grenades or infantry in elevated positions (its turret is definitely more protected than the Ta-Se but it’s not a good idea to jump into the fray)
What do you think ?
Do you have any other unit to suggest?
