PHILADELPHIA (CBS) -- Two Pennsylvania veterans have joined General John Allen's warning: that republican Donald Trump's verbal attacks on members of the military, and their families, could presage conflict with the armed forces if Trump becomes commander-in-chief.

Retired major General Gale Pollock says she's unhappy to get involved in the uproar over the republican candidate's comments about the family of Humayun Khan, who died protecting his army unit in Iraq, but says she could not stand by.

"I'm just really troubled by this. I would certainly hope that a military-civilian crisis is not in our future," said Pollock.

Her ominous statement was quickly echoed by former Navy commander Manon Trivedi, who joined her on a conference call set up by the Clinton campaign.

"I hate to say it but I would be concerned about a military-civilian crisis if he was our commander-in-chief," said Trivedi.

The veterans say the military has a duty to refuse orders they consider illegal or immoral, and Trump's criticism of Khan's parents appearance at the Democratic National Convention raises concerns about how he views the military.
