now doing the military academy is a little more convoluted and where the life path system can get a little confused.
Military Academy (830 XP + Field Costs)
Military academies represent the finest in training for career-minded
characters in the military. Every major realm boasts at least
one interstellar-grade military academy like House Steiner’s Nagelring
on Tharkad, or the Draconis Combine’s Sun Zhang MechWarrior
Academy. As the place where MechWarriors learn their craft and all
recruits are viewed as potential officer candidates, military academies
have stricter entry requirements than simple enlistment.
Prerequisite: If character did not take Prep School or Military
School as a Stage 2 module, apply the following:
[Attributes] WIL
(+100 XP), EDG (–100 XP); [Traits] Connection (+200 XP), Reputation
(–100 XP), Wealth (–100 XP) does not apply

Fields
Basic (+1 year):
Basic Training, Basic Training (Naval)
Advanced (+1 year):
Analysis, Cavalry, Infantry, Marine,
MechWarrior, Pilot/Aerospace (Combat),
Pilot/Aircraft (Combat),
Pilot/DropShip, Scientist, Scout, Ship’s CrewSpecial (+2 years): Doctor, Infantry/Anti-’Mech, Military Scientist,
Pilot/Battle Armor, Pilot/JumpShip, Pilot/WarShip, Special Forcesso I picked the basic training (naval) field, and the pilot aerospace (combat)
so we jump ahead to pg 84 where the military skill fields are, and pg 71 field costs are 30

per field with a "rebate" of 6xp per skill that goes back into the pool
so basic training (naval) requires INT 4, RFL 3, and cannot have TDS
Career/Pilot or
ships crew +30 XP
Martial arts +30 XP
Medtech/General +30 XP
Navigation/Space +30 XP
Small Arms +30 XP
Zero-G Operations +30 XP
for a field cost of 180 XP
and a rebate of 36 XP
Pilot Aerospace (Combat)
Requires: Basic Training Field or Basic Training (Naval) Field, DEX 4, RFL 4
Gunnery/Aerospace +30 XP
Navigation/Air +30 XP
Navigation/Space +30 XP
Piloting/Aerospace +30 XP
Sensor Operations +30 XP
Tactics/Space +30 XP
Zero-G Operations +30 XP
for a total of 210 XP and 42 back into the pool as the rebate
so the Military Academy training ends up costing:
830, +180, +210, - 36 and -42 or 1220 -78 or a grand total of 1142

rather pricy.
of course we could stop there but I said we were doing OCS so lets add that and then consolidate stage 3
