I say powerfull headmounted infrared spotlight for complete darkness situations. better than the 2 shoulder lights on the vf-1.
second guess would be a directional speaker so basara can sing before sound booster was invented.
ps i know sound doesn't travel in space but in the mac7 universe it does.
Actually, I think the speaker pod guns are there precisely beause sound DOESN'T travel in space.
Of course, Minmay just used the radio...
read the ps duh.
For the mac7 universe is slightly off, hence all the speakers that are built on the sound force valks and the sound boosters.
just to note im not a mac7 fan *kicks keith as he tries to hop in*
I only commented BECAUSE of the PS.
Basara had the speakerpod gun from episode 1. Which shot large and expensive stereos into enemy mechs so he could make them LISTEN TO HIS SONG, even with no air.
