But you can take out the UK BB without using the Med Fleet to do it, and probably not lose a single FIG.
1 SUB SZ8, 1 FIG Western, 1 FIG Norway, 1 FIG Germany against 1 German BB.
Odds are:
100% to kill the BB
90% w/o losing any FIGs
29% still having the SUB!
THat leaves the Med Fleet free to assist with Egypt, and the BB to absorb any potential hit from the SZ15 DST.
Taking Egypt with more force, even with bid units in Libya, is a good idea, since it potentially can prevent a UK counter, or at least reduce the UK forces present in Egypt for the G2 attack.
As for the UK fleet in SZ6…
W/o major assistance from the Luftwaffe, you lose, period.
Even using Germany’s TOTAL available resources (2 SUB, 1 DST, 1 TRN, 1 AC, 5 FIG, 1 BOM) against an SZ6 fleet of 1 AC, 2 FIG, 1 BB, 2 TRN, 1 SUB on G2 the odds are indeed good for a win (97%) but your most likely remaining forces are only 4 FIG and a BOM (1 FIG suicides from Libya due to loss of AC). That is not that great of a trade, especially since UK still has 1 more TRN in the water from start, and the US fleet will be arriving later that round to fill in the gaps.
Meanwhile, no AF was available for attacks on Norway (taken in UK1), Ukraine (re-taken by Russia in R2), or to re-take Egypt (liberated on UK1).
The opportunity cost is dreadful!
