Ever since my brother joined the Military I've thought that could be a potentially good way to push cryonics. The Military is already well-known for forcing technological change, but it's less known that the Military's effort to reduce loss of fighting men to Syphilis (as well as other STIs) was a major contributor to the social acceptance of condoms, which had previously been shunned. The social changes resulting from that campaign are often cited as a precursor to the sexual revolution.

People don't seem to care that much when an old person dies of natural causes, which is the case for most cryo. A young, attractive corpse gathers enough sympathy and attention to get crowd-sourced funding. The Military produces a much higher-than-average number of young, tragic deaths. A fair percentage of them leave the brain intact. It shouldn't be that hard of a case to make that since the Military is the reason that these young people are losing their lives, it has a duty to give them the best chance at getting their lives back.

Difficulty of engineering a moderately-sided canister that can be fitted over the head of a dead soldier and automatically sever and preserve it (obviously opt-in only)? Probably well within DARPA resources. A decade of this being a standard option for military personnel would do wonders to ease social acceptability, no? A family that has a son/brother in cryo now has emotional motivation to consider that it just might, maybe, work some day in the future.

I actually have a list of about ten of these, which I will happily make available on request (i.e. I’ll write another discussion post about them if people are interested)

I am interested, please consider this +1 requests. :)
