Just plain bad English here but the reporters seldom write the headlines and you get 'clicks' with the scary ones! For the less scary headline, put "may" as in "Army Chaplain May Face Court Martial For Sharing Christian Book On Coronavirus" or perhaps 'threatened with'. Remembering that we had 8 years of Obama, the chance of a CM is a roll of the dice.
As for this line from the article; "Together with 22 other chaplains, MRFF president Mikey Weinstein demanded that Col. Kim be court martialed for daring to send "unsolicited" copies to "subordinate chaplains," promoting a -- gasp! -- biblical message.", remember that the military now has atheist, Wiccan and (I seem to remember) at least one Satanist chaplain[s]. The military designation of chaplain is no longer what it was in Dad's Army! So if this PoS has 22 fellow travelers in this action, well I would not be likely to use them.
You are right. I did a search and there were trying times in the former administration.
