He is in charge of a multi-billion pounds budget and has his finger on the pulse when it comes to defending our nation.
But Defence Secretary Michael Fallon was caught in a different kind of crossfire today - after being accused of taking a nap during Prime Minister's Questions.
Dozens took to social media to post pictures of the Sevenoaks MP allegedly snoozing while PM David Cameron spoke.
He was seen with his head rested on his shoulder as he sat on the frontbench in the House of Commons - not before checking his phone and ears, of course
From screenshots posted on Twitter, PMQs all seemed a little too much for the 62-year-old Sundridge resident, who has been dealing with current issues including conflict with Russia and of course a sonic boom.
But his office has denied claims the man in charge of defending the nation took 40 winks at one of the busiest parliamentary sessions in the week.
A spokesman said: "It's not true, he is not asleep. PMQs is one of noisiest events there is no way he'd fall asleep, the noise in the chamber is very loud.
"It's not true. The way pictures have been frozen have made it look that way, but when watching the video it is very clear Mr Fallon did not fall asleep."
Some have claimed Mr Fallon doesn't fall asleep but merely rests his head on his shoulder while the PM answers a question.
But this hasn't stopped the pictures doing the rounds on social media with some asking how the MP could fall asleep with the hustle and bustle of PMQs.
