How Canadian Kangaroo APCs turned surplus hulls into protection

What is your assessment of Kangaroo armoured personnel carriers?

They are praised as a practical conversion of surplus gun and tank hulls into protected infantry transport, with several different vehicles sharing the Kangaroo name.

Kangaroo covers a family of armoured personnel-carrier conversions rather than a single vehicle design. The examples begin with M7 Priest self-propelled guns and extend to obsolete Ram tanks and available Sherman or Churchill hulls. Removing the main armament created room to carry infantry inside an existing armoured vehicle. The comparison with vulnerable half-tracks explains the appeal of heavier protection. Available hulls and a pressing battlefield need made conversion an attractive alternative to starting a new design. A retained machine-gun position and protection against overhead fragments are also mentioned, without clearly establishing a uniform roof arrangement across the different conversions.
