Umm, first off, apologies to Copyrite, apparently he deliberated avoided me when I was in his direct path.
Map was Icelands? (bridge you need to hit on angle and roll off to land).
No hogs at base, started walking to navs.
Got rckt launcher at bridge nav, teleported down, got nav, heading to base nav.
Was within viewing (partial) distance of base, enemy hog came past, I didn't notice on radar, noticed hog as it passed and fired and killed driver (it was a clean kill, rear of hog had just passed my left shoulder).
Question is, should I have left hog alone, and proceeded to base to locate hog?
Sorry for confusing question in-game BFM_Nova.
