Freezing an animation on a certain frame

So I have a s$$anonymous$$eld defending mechanism in my game, when I hold right click, it activates the defending and plays the s$$anonymous$$eld defending animation.

My problem is, the s$$anonymous$$eld defending animation of course has the model move $$anonymous$$s s$$anonymous$$eld arm from $$anonymous$$s side to $$anonymous$$s front... so when I hold the right mouse button, it loops, and he continuously brings it to the front from the side, rather than keeping it at the front. Is there a way I can freeze it on the frame where the s$$anonymous$$eld is in front of $$anonymous$$m?
