I think he's asking if he can become an amateur mma fighter (presumably meaning actually taking part in a fight) within a year of starting training. The answer is probably yes if its like the US. Practically anyone can get an amateur fight here as long as they pass their medicals (and in some places/situations, without even that).
Whether you'll be remotely successful, I don't know. A lot of ammies here have high school/collegiate wrestling experience so someone with only a year of any kind of combat sport training would probably be in some trouble. But I don't know what its like over there.
His helmet was stifling, it narrowed his vision. And he must see far. His shield was heavy. It threw him off balance. And his target is far away.
