Are kicking & punches similar if not the same for TKD as they are for Krav Maga?
There's huge variety in what passes for TKD - it's evolved (degraded?) from (predominantly Shotokan) karate to myriad current forms including the WTF Olympic sport, and ITF and its dubious sine wave, in just 70 years, while being spread to hundreds of countries by instructors of all ability levels with all manner of influences. There are many significant sized organisations - some with quite consistent, distinctive technique and others where seemingly anything goes.
Some styles barely punch at all, while others give it as much or more focus than kicking. That said, few TKD styles that don't explicitly claim a boxing influence emphasise hooks or upper-cut punches, nor is punching with a vertical fist common. Upset (punches into the stomach) are taught in some schools, but not utilised much in combat. These all seem common in the (relatively little) Krav Maga I've seen.
As for kicks, my impression is that many Krav Maga instructors prefer to focus on low kicks and knees, quite unlike the majority of TKD schools where kicking is predominantly above the belt. The Krag Maga instructors I've seen kick higher aren't doing anything outside the range of techniques that'd pass for some manner of TKD, but they wouldn't be mistaken for a high-level WTF or ITF practitioner, for which the stylistic elements are pretty obvious.
