Po-faced crap.
Something can be funny within a tragic event. An aspect of a tragic event can be funny.
I think it's fucking hilarious that 18 months into a war where Artillery and ISTAR has been the main vehicle of destruction on all sides, a divisional commander (30 years of training and experience) thinks it's fine to park his HQ in the open for two hours while they wait for him to deliver a speech.
It's dumber than a fucking housebrick. It's also funny as fuck because it says some very bad things about the mentality of this particular individual.
It's funny as fuck that I shit myself in a sleeping bag in a FOB in Afghanistan - I'd been out on a OP job for 3 weeks eating nothing but biscuits and pouch meals. I'd got back to the FOB, sorted my gear out, had a wash, scoffed a load of watermelon as my first fresh food in weeks, went to bed and an hour later my eyes flashed open. There was a terrible pain in my belly and before I could move my hands to the zip of my sleeping bag a hose of wild, uncontainable explosive diarrhea shot out of my arse. That's funny. I was laughing my head off while washing myself down with a bucket of water and a cloth - I burned my sleeping bag.
One of my closest friends was dead within an hour of that. It was a devastating tragedy and an absolute waste of a wonderful, loving, kind man who would set off uncontrollable giggles in everyone he met simply with a grin, or a wink.
The day was funny, and tragic. It's quite possible for both of those things to be true at the same time.
