To clear the political decks, Bob Winters beats Trudeau for the Liberal leadership in '68.
Army: Bobcat APC (cancelled in '63 IOTL) is given more time to work out its teething problems and is introduced into service by '68. Centurions are upgraded, since the budget probably doesn't have room for Chieftains.
Navy: homebuilt DDGs/FFGs, something is done about the Bonnie. Perhaps the Eagle or a CVS with Harriers in the 1980s?
Air Force: In 1969 AIRCOM recommended Rhinos to replace the elderly Voodoos, promptly axed by PET. Without him in office, the purchase goes through. KC-130s for AAR, maybe a 707 or 2 for AWACS. I would also recommend Chinooks and Hueys for air mobility, you don't need gunships.
So my questions are: how long does this TOE remain in service? Possible replacements? Any possible deployments?
