A) The PB is an armored target and only certain Inf units can attack an armored target from more than 1 hex away, such as but not limited to AA MG, AT Rifle etc. Standard Inf units can only attack an armored target when they are directly adjacent to the target hex.
B) It looks like the elevation is very high, maybe it is because of the higher elevation, harder to get up the steep slope.
