Mark Tenjer lying on his bed eventually got bored just lying there and not doing anything, he needed something to occupy his mind before the next mission. So he got up and began to put on his ODST armour, knowing he'd need to have it on soon anyways because of the upcoming briefing. After taking the time to put on his armor he grabbed his Assault Rifle & DMR which he kept on him. He walked out of his room and headed towards the shooting range, maybe practicing his aim would help keep him distracted and hopefully sharpen his skills as well. Once he got to the shooting range he pulled out his DMR, and opened out the shooting range's computer. He set it to be a timed 90 second trial with moving targets, bonus points for hitting a target's vitals. 

One coded in he aimed his DMR and quickly slammed the start button, a loud buzzer sound and the targets began to slide across. Alien noises, gun fire and human screams being imitated through the speakers. He quickly pulled the trigger, hitting almost every target in the head. [i]"One, two, three. One, two, three[/i] he counted in his head for how many times to pull the trigger on a single target. Swiftly and instinctually pulling out the magazine and reloading the moment he fired 15 rounds knowing that's when the magazine was empty. Once all his magazines were out he swiftly dropped his DMR and switch to his Assault Rifle. Now changing his focus from the head to the heart of the target he kept controlled bursts of 8 shots per target, also swiftly changing Magazines at the maximum. In this weapons case that would be 32 rounds, and before he knew it the buzzer sounded again indicating the end. He looked at the score which said 95% accuracy.

"Shoot, that 5% is gonna kill me out there" Mark said to the computer in response. He went to grab some more ammo from the small ammo storage in the firing range and then after reloading his weapons hit the buzzer to go at it again.
