I've been practicing on modeling human characters to be able to create infantries.
The one I've made isn't as properly modeled as the ones I've practiced on,
but when creating the animation sequence for it I noticed the walk animation is slower.
Compared to the firing, the firing actually shows the speed for the amount of frames it's using.

Red Alert 20 XX had smooth looking walking animations. Is there a way to achieve the same?

The original animation I've used for the infantry had 20 frames but now reduced to 7 for walking.
The firing animation on the start uses the walking animation frames and it looks the same as the one on blender when rendered.
