training course mac guyver style with unarmed ships.

is worth noting that much of the armed forces trainning or the perception of it is that ships would be armed or that the marine. infantry, and warships of planet nations or star nations would be armed.
suppose the items ready to hand were used to make traps, tear as, or that venemous insects could be deployed . various gas canisters as well to create impetus to knock away projectiles  such as mssiles.
compressed air or say a bicycle pump could d come in handy .
other  things worth noting is the objections to warfare stem from the bombing of civilians that is non combatants . the suggestions on how the bombs might be disramed while in the air has not been broached.
i know there are police bomb squads specializing in disraming bombs found. that principle could be applied to those dropped from planes orr ships from orbit . the question is how to cut the fuse or stop the mechanism which ignites the bombs. again i think a gas fired from fletchette guns in containers might do the trick. anti air craft flak guns that is. from 1945-1989 and still in 21st century people do not offer suggestions how this ight be donw.
