As a further addendum, one of my 3 top favorite 19th century Newspaper block prints of Goorkhas with kukri, {Which I bought, to frame & display alongside my kukri collection.} Its nearly 2ft wide & exhibits great skill in wood block engraving! Its a great picture to have!

{Digital copies can be found elswere on line, many original copied from my example.

Is of the Lushai expedition...
The 44th make up {not the 43rd. {mentioned in another thread.}which at that time was a seperate unit to the 44th... The clues in the number

} are mentioned in the official Army "AG circular no. 117" dated 9th september 1864.
As quoted in "The Linages & Composition of Gurkha Regiments in British Service." {published by Gurkha museam.}
So clearly a mostly Goorkha & Assam Hillmen based unit, would be highly skilled at sheltor building, rather than the 22nd Punjabis, who while usefull solders wouldnt be so used to such craft & work.
