Aim: does it apply to javalins?

[Truper]

Having developed a fondness for the school of alteration, and continuing my love affair with Vanheim, I thought I'd test out whether Aim could be used with the initial army of Huskarls to help with initial expansion. I thought it might also be a good way to get some use out of the starting Vanherse. Anyway, I bought a Vanjarl and some Hirdmen, put the Hirdmen in the front, the Huskarls behind them, and my Vanjarl and Vanherse just behnd those scripted to cast Aim in the 1st round. The Vanherse cast it on a square of Huskarls like I was hoping, though the Jarl chose to cast his on the Herse (even though he knew no spells that could benefit). When I then examined the stats of the Huskarls that had Aim cast on them, there was no change to their precision stat, but the Herse had his precision increased by 5. Does this imply that Aim doesn't apply to javalins?
