i think that the best time for germany to hit egypt would be round 1, before the u.k. could build a I.C.
without a I.C. at egypt, when playing the u.k. and trying to hold africa is impossible,
germany can call upon armor from libya, 1 infantry supported by artillery from libya, and 1 infantry, 1 armor from france, or 2 infantry from france, supported by a bomber from germany egypt could easily fall at round 1, before the u.k. had a chance to defend,
if i were the u.k. player, i would move the 2 infantry from trans-jordan > to egypt, and build a I.C. there, or the infantry and artillery from india > egypt, and there would be no need for the I.C. at egypt,
if germany has not reinforced libya, a u.k. attack at libya would be likely, that is what happens when i play, the u.k. player builds a I.C. at egypt, and germany is wiped out at north africa,
the way that i see to stop this, is to move italian infantry to libya, to bulk up the defense, it makes the u.k. player wary of overstretching their hand, and a fighter or two can throw the cat among the pigeon’s hitting at 4 defence,
also a double attack from italy and germany can soon knock out the u.k. at egypt
