When your squadleader tells you to move to "2-45", it means you have to move 45 meters in the 2 o'clock direction... Simple isn't it? ;D
In your example, you must walk/run/crawl/drive/etc. for 23 meters, at your 1 o'clock. But if this spot was near a building or a tree, your squadleader would say "Move to Bush/House/Building/Whatever, 1 o'clock!"
Do u c what i mean??
