Canada seems to have a very different way to protect military voters. They take the election to them, even in far off combat zones.  “To ensure they can [vote], five two-person teams were slated to fly by military transport to the various strong points and forward operating bases, said Maj. Kash Bagal, senior deputy returning officer. Voting booths were being set up in mess halls and other convenient locations, where soldiers could cast ballots.”
 
With a hat tip to an officer who sends this story.  This is not the first time I have received email from uniformed servicemembers complaining about the way they must cast ballots.  This one notes that even Harry Truman complained about the system. The officer notes “ENOUGH.  If we can have a navy or army band and choir, we can have a voting facilitation team.” 

Whenever ideas like this are floated, one can usually guess someone’s reaction based on where they work.  The public overwhelmingly tends to respond positively, as if this is a common sense solution.  The bureaucracy doesn’t.
