"Is there a doctor on this plane???"

"Well yes, but I defended my thesis in comparative literature..."

[1] Yes, the ribald jokes have already been made

Match play at the World Championship (where the two players play each other repeatedly for many games) involves a ton of inter-game coaching and work as each player's team goes over what went well, what went wrong, and how the next game should be approached.

Round robin play in small fields also has a significant amount of preparation because the schedule is known in advance, so players will know whom they have to play the following morning and will prepare accordingly.

I'm not comfortable saying that Hikaru does exactly 0 preparation for 3-minute Chess.com blitz games, but it's probably pretty close to 0.

I don't like bullet, but 15-minute and 3-5 minute chess is wonderful to watch.

Think of a sports fan complaining that their favorite player is rated too low by Madden or FIFA's video game representation of the stats. "Whaddya mean that Justin Herbert is only rated 91, he should be rated 97!" Except instead of pointing to some box scores on ProFootballReference to attack the naysayers, you leak classified intelligence.

An American tank using American combined-arms doctrine? Well, it's not going to be a risk-free experience, but I'd rather be in the tank than be one of the bullet sponges who are fighting house-to-house to prevent the enemy bullet sponges from sticking an AT-4 out of a window.

As other people have noted, "survivability" doesn't really factor into military thinking so much as capabilities. Bullets are extremely lethal to infantrymen, but we still have infantry because infantrymen have capabilities that other equipment platforms do not have. The existence of machine guns doesn't remove the need for infantry; it just changes how they have to be used (more cover and concealment, more need for air, artillery, and tank support). The same is true for tanks - they have capabilities that no other platform can satisfactorily fulfill, so we will continue to have tanks even if anti-armor weapons become even more effective than they already are.

Imagine my surprise when our troop went to SeaBase and ran into a bunch of other troops where everyone got Eagle at age 14.
