Read an observation about Wrath of Khan that I hadn't noticed before. Everytime Sulu opens fire on Reliant he's aiming directly at its bridge. First time he grazes it but walks the shots to its power plant. Second time the ship is jolted and its a clean miss but parallel to the bridge. Third time he scores a glancing hit killing most of Khans bro squad.
Chekov takes over then and delivers the crippling blow, but the main lesson here to take away is that Sulu does not fuck around.
Edit- Though it is also worth noting the differences between the two approaches. Sulu goes straight for the kill, coldblooded but risky. When he missed he allowed Reliant to retaliate. Chekov on the other hand as a more trained tactical officer instead killed Reliants weapons first, then its propulsion leaving it defanged and unable to run.
This is why old Trek is a billion times superior to the shite that defiles the name these days
