well here's my strategy, I just hope you don't expect me to be elaborate as Isabelle's post

here goes nothing, but how I would prefer it if my general would proofread my post before it should be taken into consideration

Firenation

Technology that needs to be researched:

Tanks

Drills

Elite Dragon Warrior training

Science

Medicine

well for the army portion I will let my general handle that much.

oh ok

4000 troops for the rough riders

7000 for basic fire nation infantry

4000 for the naval army specialist

100 out of the 4000 shall be on the dragons

100 out of the 4000 shall be on rhinos

300 out of the basica fire nation infanty will be on ships, tanks drills

300 of the naval army specialist will be on ships, tanks,drills

Since there are war balloons invinted the air temples are more vulnerable. To fix that we will need many flying bison. The bison will need armor so they can be more won't die right away.

Technology that needs to be researched:

Armor for Bison

The slug tank thing (as shown on "The Invasion: Eclipse")

Explosives

Gliders

Stink Bombs

Medical abilities

Flying Bison training.

Tornados

Infantry Layout:

2,500 men of defense

6,000 men on gliders

2,000 men on bisons

3,500 men on ground

750 men on the slug tank things

250 men on the medic team
