Uh OK, I'll give the TFTD fanfic a try.
I apologize for all spelling errors and gramatically mishaps.
Name: Gerhard "Troopi" Hafner
Controlled by: me, but since I'm not a good writer, does anybody want to join?
Joined X-Com on: depends, I thought of him as a replacement for fallen X-COM agents
Current assignment: Feldwebel [Seargent] at the Bundeswehr [German army]
Status: alive and kicking
Size: 1,86 m (6 foot 1 inch)
Weight: 90 kg (198 pounds)
Born in 2014 in Altenkirchen, in the Westerwald, Gerhard always liked Nature and hiking around the countryside. He's able to sneak up at almost any wildlife animal to watch its grace and beauty. Later in his life, he joined the Bundeswehr because he enjoyed the mile long marches around the countryside and is probably the only soldier that ever did.
Due to his size and weight they gave him the squad's cumbersome but powerful machine gun. He didn't like it that much in the beginning, but stuck w/ it because he was amazed by its rate of fire and accuracy. Being a really good marksman, his excellent eyesight even at night allows him to hit pretty much anything no matter how small it is. Except when using a pistol. He hates those flimsy inaccurate devices and they're probably not worth the metal they're made of anyway! When he said to his loughing fellow soldiers that he'd rather throw a pistol at the enemy than shoot him w/ it, that wasn't a joke at all.
Gerhard's parents died when he was 21. They were enjoying a holiday vacation on a cruise ship which sank under suspicious circumstances.
Most of his spare time consist of learning Mathematics and Physics for his study at the night school. If he isn't studying, he's around w/ his Heavy Metal buddies back then from school, drinking beer, listening to Iron Maiden or modding their bikes and cars. His buddies nicknamed him "Troopi" , a reference not only to his favourite song "The Trooper" but also to his military career. He's a social guy but that doesn't mean he drinks that much at all.
Phew, I hope I didn't forget anything important?
Edit: yeah, I did. Gerhard speaks excellent English, a little Spanish and obviously German.
