Hi, I have recently joined the forum and started playing SH3

. I'm just learning the complex game and I have a few questions. I would really appreciate a little help! Please note that I'm only 12!
1) I enjoy manual targeting but i find it hard to get accurate data. Can you give me an easy way to acquire better data please? (my hit percentage with manual is probably only 15-25%

) I have looked at videos on Youtube but find them hard to use.
2) I have the full version bought digitally from Gamestop (v1.4) and I was wondering about getting a mod that gives me more single missions. If such thing exists, would you direct me towards it please?
3) Last, out of curiosity, I was wondering about what year to start my campaign on. I would like to know a year where there are decent subs to start with but the allies won't have search planes and destroyers out for you right off the dock. Just looking for your opinion on this

.
Any help is appreciated and happy hunting!
