Japan HF and US bombers marathon (part 2)

Ki-45 missions were quite easy, lazy option was to skip Predator achievement for 4 tokens, still 9 is less than 18.
Ki-45 has an option to mount 2x 250kg bombs - their stats are same as multirole' J7Wx bombs, but bombs are apparently different and require separate development. Just like Pe-2 M-82 engines (same as in La-5, but different).

Another set of reasonable missions are for tier V B-17D:
1) 200 cap in won battle -- whole 5 frags in cap circles
2) 8 GT in one battle -- higher tier battles may be better, as there are more GTs and it's less likely
3) 2 aerial targets with turret fire in one battle -- same as for Ki-45 - SE 100 with 20mm rear gunner at tier V is a beast
4) 30 AA guns
5) 50 GT' sections in one battle
6) Expert pilot (top 3 in 2 won battles in a row)
7) 7k personal points in one battle
8) Cap 20 sectors
9) 5 AA guns in one battle
10) Cap 2 sectors in a single sortie
11) 150 cap points for GTs
12) 1500 cap points
With a bit of luck in mission 6, it all can be done without skipping any mission for tokens.

Missions for tier VI and VII planes seem like a plain token or time grab.
