the paratroops was mentioned in coalition war campaign (book 11) which also added some new skills that characters can potentially take, as well as some additional coalition OCC's
whats interesting is war campaign is a lower numbered book than lone star which means the dog boys should have access to the war campaign skills
where it matters in this case is:
RCC related skills pg 36 lone star: dog boy
communications any,
domestic any
electrical basic electronics only
espionage any
mechanical basic mechanics and automotive only
medical first aid only
military any
physical any except acrobatics and boxing
pilot motorcycle, hovercycle, jetpack, truck, and motorboat only
pilot related any
rogue none
science none
technical any except computer operation and programming
wp any
wilderness any
a dog boy gets 5 "other" skills and 8 secondary skills from the list except for the "none" areas
war campaign added (pg 60)
communications:
electronics countermeasures
espionage:
imitate voices/Impersonation
interrogation techniques
mechanical:
basic mechanics
Medical:
Field surgery
Military:
armorer
Camoflage
find contraband, weapons and cybernetics
military Ediquette
Military Fortification
Nuclear, Biological, & Chemical Warfare
Parachuting
Recognise weapon quality
Trap construction
Trap/Mine Detection
underwater Demolitions
Physical:
Hand to hand commando
swimming and fatigue note
plus a few more skills
so there was nothing stopping a dog boy from taking the skills if you chose to.
although IMO the dog boys likely should have a few extra skills added to their "core skills list"
which was:
speaks American and dragonese at 90%
intelligence +6%
radio basic +10%
pilot hovercraft +10%
read sensory equipment +10%
weapon systems +10%
Climbing +10%
Running
land Navigation +10%
wilderness survival +10%
WP energy pistol
WP Energy rifle
WP one of choice
Hand to Hand Martial arts
IMO adding Military Etiquette might make sense (until I reread the skill where it says all soldiers have it at base skill of 30% with no improvement)
of course the coalition war campaign references the rifts main book for the dog boy and they changed it a bit in the ultimate edition
