Now that I look very closely, could be different people!
Won't go too much with the BDU though, the latter pic is at an Indian secured facility. Also, I went on the standing body posture & broad physical features of the guy as time & direction of sun can cause subtle changes in photographs of the same person.
Anyways, it is confirmed that they are now roaming on ground "openly" on the Evacuation flights (in terms of not underplaying their presence while undertaking the evacuation missions)
As for assault rifle, am not very sure. A clearer picture would help. We do have all kinds of mix in terms of weapons, for Special Forces.
Reports of few HK416 to be purchased through FMS under Special Financial Powers of Vice-Chief, were also doing the rounds in 19-20.
Sorry, no clue om that.
