An expensive way to get Egypt almost everytime. Germany could place an AC and 2 TT G2 (2 TNK, 2 INF) in SZ93 and land the whole Luftwaffe in Alexandria G2. Italy could then soften Egypt with everything available I2. G3 Germany cleans the remains of the 8th army and try to hold the place with 2 TNK and 2 INF (losses attributed to planes). If UK3 counterattack succesfully, Italy retakes the place I3 and German aircrafts help hold the ground G4. After that reinforce with IC, TT, Air. But like I said earlier, it’s kind of expensive to do things that way.
Killing Tobruk (and Ethiopia) UK1 may over strech UK too much and leave Egypt vulnerable from amphibious assaults from Italy. Tarento seems safer in my opinion but loosing this battle is almost fatal for Egypt.
