V-System
V-Reversal
A standard 17f strike reversal. Guile spins and slashes the opponent, knocking them away.
V-Skill 1
Sonic Blade creates a vertical Sonic Boom in front of Guile. By performing a Sonic Boom immediately afterwards, Guile fires a powered up 3 hit Sonic Cross that knocks the opponent down on hit. Firing a LP Boom makes for a slow moving shield that Guile can walk behind, while the EX version is the fastest projectile in the game covering the entire screen length in an instant.
V-Skill 2
Dive Sonic has Guile leading forward in the air and performing a Sonic Boom midair at a diagonal angle. Unspaced, it's unsafe, but you can easily space it to make it safe. Guile can jump over lows during the animation, but it must be done preemptively. The best thing about VS2 is that it allows Guile to keep back charge while advancing forward with a projectile.
V-Trigger 1
Solid Puncher is a 3 bar V-Trigger that allows Guile to rapid fire Sonic Booms by inputting 4,6+P then pressing P repeatedly, up to 5 times. The button pressed determines the speed, with LP being the slowest and HP being the fastest. For the EX Version, he can throw up to 3 at once which move quickly and knock the opponent down on hit. By pressing HP+HK Guile can also throw a Sonic Break without requiring charge. Solid Puncher also powers up his CA into Sonic Tempest, which does more damage and is +5 on block. This V-Trigger allows him to get some long combos in the corner.
