Not at all!! That Sikh platoon could have played no role whatsoever for the simple fact that they spent the entire time being sitting ducks in an open field on the pretext of holding the LZ despite being informed by Major Sheonan of 10 Para SF that further reinforcements would not be forthcoming and being advised to either join the Paras or take up positions in the surrounding buildings!!
But Major Birendra Singh, in all his wisdom, chose to ignore everything and decided to just sit there in that field like a retard (and these are not my words but the words of the GoC 54th Infantry Division himself!!) with a predictable outcome. Come next morning, the entire platoon got wiped out one by one, except for one soul. It was basically a turkey shoot—nay, a dodo shoot!!
Well, they could always bugger out and take position in one of the adjoining buildings, just as the Paras did!! It doesn't take an Einstein to figure this out, now does it??
