Explaining abbreviations please?

hi people!

so i wanted to learn some strategies and i found some interesting guide but soon found out that i don’t understand what they are talking about!
i though that it would be helpful for newcomers (like me) to see this post, so please lets add all commonly used abbreviations or nick names in the game.

what do those abbreviations mean?

KJF (can it be 'kill Japanese fleet?) -
KGF (can it be 'kill German fleet?) -
BB (i think it’s not a bomber, cause the guide suggest buying BB and BMR) -
LUFTWAFFE PLANES (though it’s not an abbreviation i guess) -
LANT (listed with some territories) -

those i figured out, correct me if i’m wrong:

G(or UK,J,US,R)1,2,3… - Germany in round 1,2,3…
VC - victory city
NCM - non combat move
R1,2,3… - round 1,2,3…
INF - infantry
FTRS - fighter
BMR - bomber
SZ1,2,3… - sea zone 1,2,3…
MED FLEET - Meditareat fleet

thanks for help

ok, i answer a part of it by myself :-)

KJF (instead of J could be UK, G, US, or R) - kill Japan (or UK, US, Germany, or Russia) first
LANT - i guess it’s Atlantic?
ART- artilery
ARM - tanks (because it is called ‘armor’ in the original verison)

but i still don’t know what is:

DD (as some sort of unit?) -
BB (i think it’s not a bomber, cause the guide suggest buying BB and BMR) -
LUFTWAFFE PLANES (though it’s not an abbreviation i guess) -

Wow, now this link is great! A lot of unrelated stuff there but a huge help.
Thank you!
